did you have a look at Elmer?


 From their homepage:
Elmer is an open source multiphysical simulation software developed by CSC. 
Elmer development was started 1995 in collaboration with Finnish Universities, 
research institutes and industry.

Elmer includes physical models of fluid dynamics, structural mechanics, 
electromagnetics, heat transfer and acoustics, for example. These are described 
by partial differential equations which Elmer solves by the Finite Element 
Method (FEM).

Elmer has a converter to convert gmsh msh files to Elmers native mesh format.

kind regards
