   You might check into BRLcad, Sean Morrison responds to the forum 
frequently. With this app you would be able to create a 3D model to any 
degree of detail and make material assignments to all surfaces. Properties of 
the materials can also be defined. Analysis can then be carried out. BRLcad 
is also linkable separate FEA apps.

Hope this may be of use.
