I would like to port OpenFOAM over to Blender. It’s very powerful software but a mess of dependencies and rubbish documentation. An implementation within Blender would make life so much easier.
I heard more than once during that gig that “Blender is not CAD” even though we were doing everything possible to bring it closer to being so.
But with vertex values, those are created directly in Blender’s C layer, so no possibility to make those values have 64-bit accuracy if that is important to your application or external library.
I am in agreement that Blender would make a fantastic environment to pull together many open source scientific and engineering libraries, but the vertex accuracy is the one major drawback there.
