Carola Bridge Collapse Simulation, Dresden, Germany, 2024 @KaiKostack

Uploaded November 2024 | Updated September 2026, 2 days ago

Simulation of the Carola Bridge collapse in Dresden, Germany, in September 2024, performed with the Bullet Constraints Builder (BCB) structural simulation software for Blender. The model was built from plans & photos true to scale. Reinforcement and material details were partially estimated based on photos of the collapsed bridge.

For the first time, a new feature of the BCB was used in this simulation that effectively compensates for the solver-induced sagging of long structures, such as this bridge. This reduces the overall computational effort for the simulation of bridges, since usually many more computational iterations are necessary to keep the spans straight.

$Full Dynamic Fracture in Blender Prototype This video shows for the first time a complete system for dynamic shattering and fracturing simulation in Blender. It uses the crack generation approach I revealed in my most recent videos about arbitrary deformed cell fracture. Dynamic means that no precalculation whatsoever like prefracturing or any other kind of preprocessing of the geometry is being done or required. All destruction is performed on the fly during simulation.

$Brickify - Bricks, Buildings, Blender, Bullet - 3D Destruction Physics Prototype brick-shape fracture method for Blender Fracture Modifier. Brickify took 3 min to fracture. The 50 steps/s simulation took 5 min to simulate. Doubling the steps count means doubling the simulation time while increasing accuracy. Rendering took 2 days. Enjoy!
