When you use the bolt function in SImulation, the stresses around the bolt hole are fictitiously high. Similar when you bonded contact, the "edges" of the contact again sometimes produce singularity type stresses. Is there a way to make Simulation ignore these areas to get a better plot of the true max stress whether principal or shear? I know you can use "probe" to manually spot check. But you can easily miss what the true max stress by spot checking especially in 3d parts.
