I have a geometry that I want to import into SimScale but it is complaining about the geometry having gaps and self intersections (which it does). In my definition I have a BREP container before my MESH container in which you can see my Brep lines completely align on top of each other but when converted into mesh, my floor slabs and façade get triangulated differently which results into a non-manifold mesh beyond the point of being manually repairable. ( Ignore those big openings at the end of each tube, they can easily be closed in Blender)
I have tried every mesh cleaning components I could get my hands on and none seem to do the job, and merging vertices based on distance in a software like Blender gets rid of a lot of gaps ( not all ) but introduces a lot of self-intersection.
I appreciate any help, thanks.
