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. Take this with a grain of seasalt.

Some stats for nerds:
3D model - 6.3 million polygons
Simulation model - 3000 elements + 170k constraints
Simulation time - 10 h
Render time - It's just OpenGL, ~1 s per frame
