Reply To: Force Convergence Issue in Solder Joint Reliability Simulations

[Harshil Goyal]

Hi Peter,

Quick question: I was able to converge the solution, but I'm not getting the expected results. The total deformation on the Yz plane differs from that on the Xy plane. However, the expected deformation should radiate outward from symmetric corners. I'm not sure what's happening, but I suspect it could be due to the boundary conditions. Do we only need to apply displacement, or is there something else I need to define for the symmetric plane? I read on an online forum that the symmetric face should be applied as a symmetry region in the model in Workbench. Should I add the symmetry region to my analysis, or is applying these displacements as boundary conditions sufficient? If not, how can we apply the symmetry region in Workbench, and if I apply that, do I need to remove displacement as my boundary conditions, or should I still keep it as part of the analysis?
