Blenbridge
Finite element mesh from Blender objects.
Hexahedral finite element mesh from Blender. Fun! Useful with Elmer, Calculix, Gmsh, IA-FEMesh, Febio, others. Documentation available here in PDF format, or on the locally hosted Blenbridge website in HTML format. Video tutorials are also available.
(Additional console versions are available for linux and windows, with fewer features but with greater execution speed, and the advantage of being scriptable.)
