Free non-linear FEA Solver?

Free non-linear FEA Solver?

(OP)
Hi there,

Does anyone know of any good free non-linear FEA solvers for windows? I'm a materials engineer by degree, but I'd like to start using FEA for some side projects I'm currently working on.

Thanks,
M

CalculiX is probably the best bet. Code Aster is another option. LISA is free for smaller models; there is a node limit which you have to fork over $80 to exceed.

Here's a list of freebees:

Opensees is intended for seismic analysis of structures, but it seems to me it would make a good general purpose program as well, free and open-source, and seems to be still well supported:
