Default Real-time CFD?

Hey all

For my MSc final project I'm trying to do a simulation of a bullet hitting a gelatine, which is often used in the field of wound ballistics. I have a feeling CFD could be used for this. Am I right?

Secondly, would it be possible to do a real-time simulation by simplifying the maths or using a small grid? It doesn't have to be accurate, I just want to show the visual effect.

Thanks for your time

P.S. For those interested, my MSc is Games Programming (hence the real-time requirement) and this project is is supposed to simulate a bullet hitting an apple as seen in this video: I doubt I can get anywhere close, but that's fine

You need to get familiar with the most amazing software, plasma-pong,

With the sandbox feature you might be able to set up a directional source but no chance of solid/solid interaction.

Yes, it's called conservation of momentum and energy. The rest should just be a coding exercise.

Think in terms of a billiard ball problem. Take the bullet's kinetic energy & momentum vector and transfer it to "N" particles of the apple. Add in a randomly seeded dispersion cone & you should be rocking.

If you're after physics simulations that look good (qualitative over quantitative) then particle simulations (as used in CGI movie effects) should be good enough. Real-time calculations for limited "physics in a box" are possible on GPUs. For more details try:
