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.

The BCB is a structural simulation software developed for building collapse simulations and this is the first time it is used to simulate a vehicle. The goal is to make vehicle simulations more realistic by using real world parameters and by simulating every piece of the car physically.
Having said that and before you ask, this is not a game. Perhaps GTA X will support this in 20 years but current hardware is not there yet, sorry. :)
Some stats for nerds:
Car - 1.8m triangles in 3k elements connected with 100k constraints
Simulation time - 8 sec. per frame (32 min. per 10 sec. simulation time)
Render time - It's just OpenGL, 1 sec. per frame

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.

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.

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.

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. Nothing is animated by hand.

2020-08-10 Tower 4 auxiliary main cable north comes loose from the socket (#301)

Technically the black hole consists of stacked spherical meshes with different radii to serve es volumetric ray intersection samples that would modify the light path depending on the spatial force field strength. To keep render times low a maximum of 40 transmission bounces per pixel were targeted at the cost of some accuracy. The video took two weeks to render on a GTX 1080.

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 concrete
Total length: 260 m (850 ft)
Width: 7.2 m (24 ft)
Height: 10 m (33 ft)
No. of spans: 5
Pylons: 4
Date of original: 1908
Rebuilt: 1945–1949
Collapsed: April 8, 2020

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/jVE3YwRgU9k

Kostack Studio was not involved in the making of these simulations.
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.

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.

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. Our virtual collapse simulations are based on real physics and represent the reality to a high degree.

I'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. :)

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.

A comment in the code explains the problem: "If some [neighbors] aren't taken into account, the forces will be biased by the tree search order. This effectively adds energy to the system, and results in a churning motion. But, we have to stop somewhere, and it's not the end of the world. - jahka and z0r"
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.

Descrizione (traduzione automatica):
Video del crollo del ponte Morandi rispetto alla simulazione
Due settimane dopo il crollo del ponte Morandi abbiamo rilasciato una simulazione di crollo basata sulla fisica e oggi è stato rilasciato un nuovo filmato che ci offre l'opportunità di confrontare i nostri risultati con la realtà.
Si noti che questa è ancora la nostra simulazione originale appena resa dalla nuova angolazione della telecamera. 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.
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.

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."

I'd like to emphasize the fact that these scenes are completely random results of the development process and for the most part basically represent undesired outcomes. I don't expect you can make it through the entire video but I wanted to share all the pain with you.

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. Take this with a grain of seasalt.
