I have an assembly I'm trying to analyze that has several formed plates welded together. I had done this analysis several months ago and got realistic results, but I had to rerun the analysis this week due to a change in the profile of one of the plates and now the results don't make any sense.
If you take a look at the first picture you can see that the weld is showing high stress along one edge while it is showing a fairly even stress in the second (original) picture. This is the exact same analysis with the exact same loading conditions. The only difference is that I changed the profile of one plate slightly and updated the mesh.
After having this issue I tried recreating the welds but I'm still getting the same results. Does anyone have a clue why this would be happening or what I can do to try and resolve it?
