Boolean not working, use of Nonmanifoldmerge (solved)

beam.3dm (2.3 MB)

I have to do the Boolean difference of ellipsoids from a rectangular beam structure but the ellipsoids do not touch the surface of the beam (they are inside). I tried using Boolean difference but it didn’t work; so I used NonmanifoldMerge and CreateRegions. However, when I try to mesh the resulting solid in Ansys, I have an error saying that “The surface mesh is intersecting or close to intersecting, making it difficult to create a volume mesh. Please adjust the mesh size or adjust the geometry to fix the problem”. I would really appreciate anyone’s help in fixing the geometry. Thank you.

Hello - the object has zero thickness where the ellipsoids touch the walls - Move them in or out to either have wall thickness or a hole.



That worked, thanks!
