Respected sirs:

I have implement a computer code to trace the free surface based on VOF on rectangular Eulerier grid.

Problem: I want to add the ability to simulate solid rigid objects being thrown into the fluid. The free surface many have large deformation. This simulation is for computer graphics so that I do not need very good accurancy but expect efficient algorithms.

Please suggest some references. Thanks.

we had this discussion before in the forum. Please search for VOF and MAC

Check the group of Professor Veldman at the University of Groningen:

http://www.math.rug.nl/~veldman/cfd-home.html

They have thrown several objects in fluids.

Good Luck, Pascale

Thanks. I've already performed a search before posting this question, but the returned articles are on immersed boundary method or moving mesh.

My problem is on Eulerian mesh (fixed) and the boundary is rigid (not elastic) and may move very fast w.r.t. fluids.

Try using sph methods/gridless methods. I have some papers if you are interested.
