Can someone please help me out here. When I do this analysis, if I refine the mesh, the output lb/in values increase. Aren't these values supposed to be mesh "insensitive"? Obviously this is an issue as the calculation then tells you you need a bigger weld if you have a more refined mesh. What am I missing here? Thanks in advance.
The stress values typically increase at sharp corners when refining your mesh, up to a certain point. Is your problem at a sharp corner? In real life there is alwast a small smooth transition at the weld toe. If the stress goes to infinity the more you refine your mesh, then you have a stress singularity
