I couln'd help to read more about the FEM Module, netgen and calculix. My understanding is for an appropriate FEM mesh you need appropriate input date means for shell meshes you need some plane shapes like faces and for an beam mesh (truss calculation like pyBar) you need some 1D axis. At the end, if we would like to generate a mesh what is not a volume (solid) mesh we need the axis stuff yorik made a mantis entry for.

It seams for now pybar is the solution which is easier to get results with.

But one day if the fem wb is ready to use even with beams an shells we are capable of calculating everything what we could model directly from CAD. Something like this probably. http://www.ingware.ch/referenzen/massiv ... orenz.html
