GB input 1 and 2 have 1lbf applied in the X and 1 lbf applied in the Y directions. GB input 2 is 180 out of phase from GB input 1.&nbsp;&lt;br&gt;&lt;br&gt;All contacts are bonded.&nbsp;&lt;br&gt;&lt;br&gt;I would like to be able to output a force reaction vs frequency plot for the connection to the bottom plate. I&#8217;ve turned on nodal forces, and set &#8220;expand results from&#8221; to &#8220;modal solution&#8221;. Is this approach incorrect? The simulation will not solve.&nbsp;&lt;br&gt;&lt;br&gt;I did notice workbench generated output parameters for the frequency response. Would anyone be able to provide a reason for why this happened? This is my first time seeing the parameter interface.&nbsp;&lt;br&gt;&lt;br&gt;Any insight or suggestions would be geatly appreciated.
