Star Collision Experiments with Smoke & SPH Simulation in Blender Kostack Studio 2019-12-07 | Some attempts to simulate star collisions in Blender using only the available tools.The first few sequences are using the smoke simulator with a force field attracting density. However, the simulation has problems with preserving density on larger forces and on collisions in general. Further there are artifacts causing these characteristic fountains along the axis. Another restriction is that you can't disable air drag to replicate a vacuum.The last test was a SPH particle simulation using self attracting particles to replicate gravitational attraction. The particles were remeshed using metaballs and a volume shader together with particle emissions was used to colorize the mesh depending on velocity.I also tried Elbeem fluid simulator just to learn that it doesn't support force fields at all. With only one predefined gravity vector available there was no way to simulate self attracting spherical structures like celestial bodies - not very flexible unfortunately.Music: Evergreen by Lamprey (CC BY)Made with Blender
VFX City Destruction Scenes by Stable Video Diffusion AI #SDXL #SVD Kostack Studio 2023-12-15 | I wanted to know if Stable Video Diffusion can be used for collapsing buildings and destruction scenes. Taking a few keywords and numbers into account, SVD created these scenes overnight. No 3D models, smoke simulations, or manual animations were required to create this video, just AI.Conclusion: As you can see, the scenes are mostly stationary. The process of a building collapse cannot yet be “simulated” because the system is unable to determine which parts of a structure would have to collapse. But I can imagine that future AI models will be able to even estimate cause and effect.Credits:Music: UNIVERSFIELD - Atmosphere for Documentaries (CC BY)Software:ComfyUIStable Diffusion XL TurboStable Video Diffusion

HIMARS Simulation - Olenivka Prison, Ukraine Kostack Studio 2022-11-29 | Simulation of the Oleniwka prison destroyed in Ukraine in 2022, performed with the Bullet Constraints Builder (BCB) structural simulation software for Blender. This collapse simulation was made based on the presently available data. The model was built true to scale based on photos of the destroyed building and material properties were estimated.An explosion took place at the Russian-operated Olenivka prison in Ukraine in July 2022, killing 53 Ukrainian prisoners of war (POWs) and leaving 75 wounded. Both Ukrainian and Russian authorities accused each other of the attack on the prison. Ukrainian officials said that the Russians blew up the barrack in order to cover up crimes, while the Russians suggest that a HIMARS rocket was shot from Ukrainian territory.To narrow down the cause of the destruction, this video shows simulation results for different scenarios based on the claims. The characteristic of the observable damage or debris pile compared to reality can often provide an indication of what likely happened.Conclusion:In all tests, the simulated destruction caused by the detonation of a typical HIMARS missile warhead would have far exceeded the damage to the building that can be observed in reality, which rules out the use of HIMARS in this case. Alternative causes of the explosion seem more likely, such as a smaller-sized improvised explosive device.Credits:Music:Sergey Cheremisinov - She-Wolf In My Heart (CC BY)Made with Blender + BCB + Fracture Modifierblender.orginachuslaurea.wordpress.comgithub.com/KaiKostack/bullet-constraints-builderblenderartists.org/forum/showthread.php?343637-Custom-Build-Blender-Fracture-ModifierThe "BCB" structural simulation software has been developed at the Laurea University of Applied Sciences, Finland.

Surfside Collapse Air Pockets Visualization | Champlain Towers Condo Miami Florida [8K] Kostack Studio 2021-07-27 | This video follows up on our earlier simulation of the Champlain Towers South collapse in Surfside, Florida (youtu.be/HPwJ0JvTcg8). It demonstrates the formation of air pockets within the collapsed structure allowing to identify potential zones of interest for search and rescue teams to plan escape routes or adopt first aid strategies for the rescue of victims.The simulation result can be post-processed to visualize cavities within the debris heap. In this analysis empty space is represented by color-coded bubbles allowing the assessment where big enough air pockets for survival may possibly have formed.Even though the initial distribution of the dummy dolls has been randomized and thus they cannot be used to trace back the fate of individuals, it can be observed that most of them ended up in very dense areas with very little chance of survival.The authors hope to not distress relatives of victims with the application of dummy dolls in this simulation that have the sole purpose of tracking victims in potential cavities within the debris.Credits:Simulation & video by Kai Kostackhttp://kostackstudio.deMade with Blender + BCB + Fracture Modifierblender.orginachuslaurea.wordpress.comgithub.com/KaiKostack/bullet-constraints-builderblenderartists.org/forum/showthread.php?343637-Custom-Build-Blender-Fracture-ModifierThe "BCB" structural simulation software has been developed at the Laurea University of Applied Sciences, Finland.

Condo Collapse Simulation | Champlain Towers South Surfside, Florida, Miami [8K] Kostack Studio 2021-07-17 | On the 24th of June 2021 at night the Champlain Towers South, a 12-story beachfront condominium in the Miami suburb of Surfside, Florida collapsed partially. This collapse simulation was made based on the presently available data, eyewitness, and video accounts.The authors are independent researchers and impartial hoping to constructively contribute to the fact-finding. This study demonstrates the collapse mechanism assuming the following plausible hypothesis:According to the data, the basement deck showed signs of extended soaking for many years. The problem was locally insufficiently patched and not rectified in its entirety. The wetting caused the deck ceiling to be weakened to such an extent that basement pillars punched through the deck where additional load had peaked at the planter area.The authors hope to not distress relatives of victims with the application of dummy dolls in this simulation that have the sole purpose of tracking victims in potential cavities within the debris.Air pockets visualization followup: youtu.be/XkwHxVGKQKUThe Bullet-Constraints-Builder simulation software is open-source, it was developed within the EU FP7 funded INACHUS framework.Kostack Studio was supported by Architect Oliver Walter with the data analysis.Main sources:youtu.be/KR29pLccutY8777-collins-avenue---preliminary-review-plans-for-40-year-re-certification.pdf8777-collins-ave-1979-plans.pdf8777-collins-ave---unverified-inspection-report.pdfCredits:Simulation & video by Kai Kostackhttp://kostackstudio.deConsultant: Dipl.

Arecibo Observatory Collapse Simulation [8K] Kostack Studio 2021-06-11 | This is a structural simulation of the collapse of the Arecibo Observatory in 2020. The simulation implements the three major failure events which ultimately led to the progressive failure causing the platform to fall into the dish.The simulation is based in part on actual physical data such as mass and strength for the larger components, and in part on plausible estimations. What appears to be multiple simulations at different points in time is actually one large global simulation. Deviations from reality are to be expected due to the fact that the simulation software runs completely autonomous, only the main initial failure points have been triggered by a predefined script.

Atomic Explosion 3D Reconstruction From Original 2D Footage Kostack Studio 2020-08-29 | This video shows my attempts to create a 3D shader which converts the original footage from a nuclear detonation into a volumetric representation of it. The underlying premise is that the object is cylindrical in shape. If that's the case, you can transform the UV space accordingly to turn the 2D image into 3D. The footage is mapped around an imaginary cylinder and multiplied by another instance of the texture mapped along the cylinder's tangent, which provides the silhouette. It's no nuclear science, it just requires some math. 🙂Footage from Operation Teapot / PostFilm numbers used: 29010, 29043Test conducted: April 9, 1955Source: Lawrence Livermore National LaboratoryMusic: Quaro - Psion (CC BY)Nolan Oppenheimer

Albiano Bridge Collapse Simulation, aka Caprigliola Bridge or Ponte di Albiano Magra | BCB Kostack Studio 2020-04-25 | Simulation of the Caprigliola bridge collapsed in Albiano Magra, Italy, in 2020, performed with the Bullet Constraints Builder (BCB) structural simulation software for Blender. The model was built from plans & photos true to scale. Reinforcement information was estimated in part from photos of the destroyed bridge.In the morning on the 8th of April 2020, the Albiano bridge in the region of Tuscany collapsed with only two vehicles on the road deck. The original bridge that was built in 1908 pioneered the construction of reinforced concrete bridges in Italy. The Venetian engineer Attilio Muggia designed the bridge with five slender arc structures spanning each ca. 52 m and four Pylons in the riverbed of the Magra river. The Pylons had strong vertical extensions that carried part of the road deck weight.The bridge was damaged by mines in 1945 during the last days of the second world war. It was reconstructed after the war when building material was scarce, only the base of the pylons was reused. Instead of sufficiently dimensioned arcs, the new bridge design displayed arcs with tapering cross-sections at the bases, which were connected pairwise at opposite sites of each pylon. The tendency of low and wide-spanning arc structures to prolongate at the base was most probably not sufficiently considered, by offering enough resistance against horizontal forces. Furthermore, the debris of the broken arc bases appears to display little reinforcement iron this might be due to the material shortage at the time of the reconstruction. Stronger arc sections at the bases with more iron would have strengthened the structure.We have simulated this collapse after careful analyzes of the image and video material that was posted online after the accident. This simulation assumes that material fatigue at the base of the second arc at the first Eastern pylon triggered the progressive collapse. This is a hypothesis that might help in the discussion to determine the reason for the collapse.Our simulation method is based on the Discrete Element Method (DEM) that was developed during the EU funded INACHUS FP7 Project (607522) framework. It uses the open-source “Bullet Constraints Builder” addon for the 3D Blender software.Details of the bridge:Material: Reinforced concreteTotal length: 260 m (850 ft)Width: 7.2 m (24 ft)Height: 10 m (33 ft)No. of spans: 5Pylons: 4Date of original: 1908Rebuilt: 1945–1949Collapsed: April 8, 2020Credits:Simulation by Virtual Validation CorporationKai Kostack, kostackstudio@gmx.deDipl.

Simulation Corona in Deutschland/Germany - Prognose/Prediction Kostack Studio 2020-03-21 | These are the results of a simplified spreadsheet based simulation on how the coronavirus SARS-CoV-2 will distribute infects within a specific country. The initial growth is derived from real-world case numbers and from there the simulation continues to compute new cases. In this experiment I have changed the growth factor accordingly to the plans of the German government to enforce a curfew. According to this simulation it appears to be an absolutely necessity to do so in order to get the virus under control again. Let's hope for the best!Music: Yusuke Tsutsumi - Untitled #4 (CC-BY)
All Simulation Results | University of Alaska Fairbanks, UAF | Hulseys Evaluation Project Kostack Studio 2020-02-09 | In 2015 Dr. Hulsey from the University of Alaska Fairbanks started a study on the collapse of the Building 7 of the WTC complex, this video is an overview of his struggle to provide the simulation results his client has asked for. All the video sequences shown can be found in his dataset release, which is basically a huge unordered data dump of his working directories.The videos were in a bad condition, extremely low in resolution and sometimes even corrupted, containing more frames than standard video players would show. The image quality has been improved using modern AI-based image scaling methods and all video frames are displayed for documentation purposes.I haven't digged into the source files much because it's extremely time consuming and likely not worth it. However, from visual inspection I'm pretty much convinced that Hulsey's work hasn't fulfilled the promises being made to outclass the simulations from NIST regarding accuracy and methodology - just to say this in the most diplomatic way.But I think it's interesting to see nonetheless. It reminds us of the achievement NIST has accomplished in 2007, and in the fact that even now it's hardly possible to compete with them on simulating this building.Here is my earlier plausibility check of the final videos: youtu.be/jVE3YwRgU9kMick West made a video dissecting the sims in more detail: youtube.com/watch?v=7OClixCTdDwMade by Dr. Leroy Hulsey + Team using SAP2000 and ABAQUS, funded by AE911Truth.Sources: http://ine.uaf.edu/wtc7Kostack Studio was not involved in the making of these simulations.
Nostalghia Ship Destruction Film Premiere at Helsinki Art Museum & LUX Helsinki & Opera House Oslo Kostack Studio 2020-01-17 | This video shows impressions from the Nostalghia artwork by Jaakko Niemelä. For this project we were commissioned to simulate the destruction of a huge container ship and capture the different phases of its decay. The simulation was done with Blender.Jakko Niemelä is a Finnish artist who has made destruction and the decomposition of structures an essential part of his art-making. During the past seven years, he traveled the oceans tracking his father´s routes who was a ship captain. Jaakko never really got to know his father and as a child often imagined the dangerous situations he might be in during his trips. With the Nostalghia project, Jaakko processes his fears and the relation to his father.Nostalghia is shown from 14.12.2019-15.3.2020 at the Helsinki Art Museum, HAM. The installation at HAM displays a huge illuminated scaffold structure with sails that are blown by wind machines.

Steel-Truss Pedestrian Bridge Collapse in 2016, Kuala Lumpur, Malaysia | Simulation Kostack Studio 2019-11-16 | In 2016 a 70 meters long steel-truss pedestrian bridge has collapsed. We have simulated what happened. The bridge had an unusual design with the center of gravity lying outside of its own footprint. Increasing temperatures induced internal stresses that couldn't be compensated by the bearings. As a result the bolts of the bearings holding the bridge in place have been sheared off. Without any further restraint to the uplift load the bridge had to topple and collapse.The half-completed pedestrian bridge to connect the KL Eco City to The Gardens shopping mall in Mid Valley City failed on Nov 29, killing one construction worker. We have been investigating this case by means of computer simulation to reproduce and visualize the collapse dynamics. Our virtual collapse simulations are based on real physics and represent the reality to a high degree.Credits & Links:Virtual Validation Corporation:Kai Kostack,kostackstudio@gmx.de&Dipl.

Acting Loads Simulation on 11-Story Building Collapsed in 2014, Moulivakkam, Chennai, India Kostack Studio 2019-11-02 | This is a follow-up to our analysis of the collapse of an eleven story apartment building in Chennai, India, from 2016. See the full original here: youtu.be/yu2bQtIS69gIn this video we have measured the forces acting on each column of the building before the collapse.After heavy rain on Saturday, June 28, 2014, the eleven-story under-construction building at Moulivakkam in the suburb of Chennai, Tamil Nadu collapsed, killing 61 people, mostly construction workers. We have been investigating this case by means of computer simulation to show side by side the differing outcomes of collapse simulations that represent the opposing theories.

Corona - Making a Star: The Sun Kostack Studio 2019-10-19 | The first idea was to use procedural volumetrics for the sun to avoid a hard surface look. Ultimately however, I found myself spending a lot of time on trying out different approaches to get as close as possible to real photos and videos of the sun corona. I can say now that the sun is probably the most complicated thing to recreate I have seen so far. The shapes the filaments are forming and the trails of matter flowing along magnetic field lines are very hard to get right. I used these videos as references: Fiery loops: youtu.be/HFT7ATLQQx8?t=92Solar flares / filaments: youtu.be/6tmbeLTHC_0?t=428 I have tried to replicate most effects, some with particle physics, others with procedural shaders, I have written a script to generate the trails from particle paths, and I even discovered a way how to create realistic magnetic field lines in a volume shader - see the community tab for an image:youtube.com/channel/UCozprHAh-CPdkla4E4MtOIA/community?lb=UgzrDmhTDAai-3tCLap4AaABCQI'm not entirely satisfied with the result as it still appears to be artificial but the math required to get it right is just mind-blowing. I hope you like it anyway. :)Visuals by Kai KostackMusic: I Can't Remmber I Can't Recall - The 129ersAnimated and rendered in Blenderhttp://kostackstudio.de
UAF WTC 7 Evaluation Simulation Plausibility Check (Leroy Hulsey, AE911Truth) Kostack Studio 2019-09-08 | Now that Dr Leroy Hulsey from the University of Alaska Fairbanks has released his simulation work from the past four years and people are flooding my comment sections sharing it, I have decided to make a short video showing why it is inferior to the NIST simulations.By visualizing the dynamic motion of the structure from the color change of the pixels it is possible to see even very small (subpixel) deformations. You'll notice that the building in the UAF simulations is not moving at all even when the "penthouse" is crashing down. No motion means that there is no dynamic response (no propagation) of the initial impulse observable within the structure. This would be highly unlikely in reality but confirms the observation that parts of the structure are allowed to intersect each other without collisions. It can be concluded that resistance is completely ignored within the UAF simulations, which makes them questionable and inferior to the NIST simulations.But how does it work? In reality and in FEA simulations forces will lead to displacements. Pixel colors allow to detect even very small displacements because of aliasing. This doesn't mean that this visual data is comparable to FEA data, it's obviously not, but it's more than enough to detect if there is any displacement. The point of this video is not to derive accurate data from pixels but to detect if there is any data at all. Zero pixel changes mean zero forces, or basically an invalid simulation.Mick West made a longer video dissecting the sims in more detail: youtube.com/watch?v=7OClixCTdDwOriginal UAF videos: http://ine.uaf.edu/wtc7

Morandi Bridge Collapse Footage Comparison to Simulation for Validation | BCB Kostack Studio 2019-07-01 | Two weeks after the collapse of the Morandi bridge we have released an early physics based collapse simulation and today new footage has been released giving us the opportunity to compare our results to reality.Note that this is still our original simulation just rendered from the new camera angle. While there are obvious deviations there are also striking similarities observable. Given the fact that at this time it was completely unclear what has happened and that we only had limited knowledge about the structure this is a pretty close result.Our original video: youtu.be/Y6suQ0FIoIQFootage source: Guardia di Finanza GenovaSimulated with BCB: github.com/KaiKostack/bullet-constraints-builderBCB blog: inachuslaurea.wordpress.comThis software is developed at the Laurea University of Applied Sciences, Finland.

Mentre ci sono evidenti deviazioni ci sono anche somiglianze sorprendenti osservabili. Dato che in quel momento non era chiaro cosa fosse successo e che avevamo solo una conoscenza limitata della struttura, questo è un risultato piuttosto vicino.
Tornados on Mars | Dev Reel Kostack Studio 2019-06-14 | Making a tornado is one of the biggest challenges in VFX, so I made two. ;) Just kidding, but it's actually more difficult than I thought. If you don't believe me, download Blender and try to make one. Now I have whole lot more respect for the VFX teams that made "Twister" and "Mission to Mars".I first tried to use particles to get a more granular look like in the mars movie, but I soon realized that this many particles wasn't something Blender could handle, also the render times became ugly slow. So I switched to a smoke simulation which also helped to achieve more natural dynamics. Instead of using high-res smoke I simulated only with low resolution and added the details as shader, that saved a lot of memory.The landscape is entirely shader generated and completely procedural as well. It is mapped onto a sphere, so that you can actually move the camera far away from the planet to see its shape.Visuals by Kai KostackMusic:Valiant by PeriTune (CC-BY)Unknown World 2 by PeriTune (CC-BY)Animated and rendered in Blenderhttp://kostackstudio.de

EarthBlend - Planet Simulator Demo #1 - Atmospheric Flow Kostack Studio 2019-03-22 | Atmospheric flow simulation using 2D Lattice Boltzmann method (LBM) seamlessly mapped around a sphere in Blender - Inspired by the old video game SimEarth from 1990, I thought it would be interesting to start a little side project to replicate the major dynamics of a planet using some math and a simplistic model.It's not about making an accurate weather simulation but more about a global simulation on the development of atmospheric gases, temperature, and plant growth over a longer period of time. I'm interested to play around with the interdependencies to learn more about the climate system. I basically hope that ultimately I will be able to visualize the Gaia hypothesis:"Topics related to the hypothesis include how the biosphere and the evolution of organisms affect the stability of global temperature, salinity of seawater, atmospheric oxygen levels, the maintenance of a hydrosphere of liquid water and other environmental variables that affect the habitability of Earth."en.wikipedia.org/wiki/Gaia_hypothesisMusic: Boat Floating - Puddle of Infinity (YT Audio Lib)

Submarine Implosion + Sinking Simulation of the ARA San Juan | Similar: KRI Nanggala 402, Titan Kostack Studio 2018-12-15 | This is a structural simulation of the last moments of the submarine from Argentina you probably have heard of. The simulation utilizes new program code for drag and pressure simulation of water to reproduce the dynamics that have acted on the pressure hull. Physical parameters like scale, mass, pressure, density of the water are accurately simulated.The structure itself, however, was so complex that it has been discretized more roughly in order to keep simulation times practical. While volumes and connection areas of the individual elements are still accurately computed from geometry, joining structural elements like that can only be seen as an approximation of the real world and thus deviations are to be expected.
