Hi respected colleagues!
While trying to form a second union of domains components in a 3D COMSOL model, I was met with the the response "Error while building 'Union 2' in Geometry: Boolean geometry operation failed".
Could this situation be caused by the multiple tangential boundaries in model? If yes, how can the tangential problems be tackled in a model?
I attached a screenshot of the response for your kind considerations.
Looking forward to your meaningful contributions.
Thank you.
