Is this a welded frame? Welds are sort of complicated to analyze, and, depending on evaluation technique, it may not be necessary to remove the singularities. According to evaluation technique of "nominal stress" (if applicable), or "hot spot method" you do not need to remove singularities, since stresses are not evaluated at those locations.

I wrote a few words about weld evaluation here: How are others calculating Welds in Creo Simulate?
