FEM library for realtime app

Do you know any library for Finite Element Method, that i can use for realtime application ? I think about getFEM++, but I don't test it yet.

I want to use FEM to simulate behav开发者_开发百科iour of elasto-plastic body in realtime. My further plan is to merge it with Bullet.

You should try to specify the kind of problems you are trying to solve in order to select the best library for you.

• How many dimensions for your problem?
• Do you plan on doing collision detection?
• How many vertices will compose your objects?
• Do you plan on using parallelism to achieve real-time computations?
• Do you plan on doing spectral analysis for a dynamical system or just study local deformations with a quasistatic system?
• etc.

Concerning the available libraries, I have mostly used homemade ones, but here are some that you might be able to use:

• [GetFEM++] : C++ library, documentation and tutorials available. It seems you already know this one.
• [LifeV] : I know some people who use this for fluid dynamics, but it works for structure dynamics too. It is developed by several major research institutions.
• [OFELI] : another C++ library but it may lack tutorials.

Moreover, are you sure that what you need is not already present in the Bullet library? Soft body dynamics is already a part of Bullet... (Video here)
