If you have a 64-bit computer CAELinux if a free open source option. It comes with the open source for details. I'm not too strong on the solid mechanics side but my understanding is that the solvers (with Salome as the geometrt/meshing tool) like Code-Aster are for linear elasticity. For developing your own non-linear solvers you would ideally do it yourself using C++ libraries like deal. The deal.ii library is very good and it won the Wilkonson prize for numerical software. I am thinking of seeing if I can write a non-linear FEM solid mechanics code later this year.
For fluid mechanics codes the underlying PDEs are coupled convective-diffusive by definition but the radial basis function approach is starting to look quite promising for straight non-linear analysis, and its nicer because unlike the FEM approach the dimensions of the underlying PDEs can be higher than three.
