This is a call for Blender science/engineering community people: I’ve been wondering about possibility to use Blender for creating, viewing and editing of volume meshes. That would make Blender a preprocessor for finite volume or finite element analysis (for various kinds of scientific computing and simulations). Blender already has good capabilities for editing surface meshes (vertices, edges and faces), but I wonder how hard it would be to adapt the framework to include also polyhedral cells (volume elements). This involves the concept of “internal” faces, edges and vertices, which are shared by neighboring cells, and “boundary” faces, edges and vertices, which are not. Has anyone already considered or tried this?
