Re: FEM MeshBoundaryLayer Documentation discussion thread

I do not use it. Would be good to have an useful example file which shows what this is useful for. I looked in the source code and it seems like you coded it, amirite?

Re: Brep IFC export should be ON by default?

if a solid is exported as brep it is just a bunch of faces. this is not smart because noone knows the thickness and the height of the wall later on. If it is exported as extrusion it is a line or polyline with a thickness and an extrusion length in z-direction. If a wall is not exported as extrusion...

If you nean a single Shape than yes the mesher could only handle one Shape. But a Shape could be a Compound and a Compound could be made from everythin...

Re: FEM mesh: Create mesh groups in Python (exposing C++ functions to Python)

... is there any useful documentation how to extend the functionality of FemMesh or other C++ classes? ... no, just the code ... I had to put it all together by recycling other functions from the code, which is maybe not the best way of development :-) :mrgreen: ... it is exactly the same way I hav...
