I&#8217;ve assigned 2 separate frictionless contacts, as the teeth undergo different stress levels depending on the direction of applied torque. This allows me to get average contact stress values for a high side and low side of the teeth, but I&#8217;m seeing some unwanted stress concentrations at the edges (as expected). I do not want these included in my results. As such, I&rsquo;ve created named nodal selections to exclude these singularities, but I&#8217;m unsure how to generate a contact pressure result.&lt;\/p&gt;&lt;p class=&#8221;MsoNormal&#8221;&gt;I can re-run with contacts defined by the named selections, but I&#8217;m afraid it will just move the stress concentrations inward as I&#8217;m essentially just redefining the edge, right? If this understanding is wrong, please let me know.&nbsp;&lt;\/p&gt;&lt;p class=&#8221;MsoNormal&#8221;&gt;Any insight on how to generate these contact pressures without including the edge nodes would be greatly appreciated.
