By the way, it seems that all that bonemat can do you can already do in Slicer. For the parameter mapping from CT densities to mechanical properties you can use a few lines of Python code (or using py_bonemat_abaqus). The license of bonemat is quite restrictive and you can do so much more in Slicer that I would recommend to consider using just Slicer for your workflow.
