This is not my video. I found it on the web. Thought it would be interesting to the community. This is a 2d CFD simulation of a supersonic bullet fired down a pipe, made using a special version of VH1 that can simulate flow around rigid objects.The solver is PPM-LR, piecewise-parabolic method (Collela & Woodward), with a Lagrangian remap. |
