I am using a command block in the solution portion of Ansys Workbench. I am unable to retieve the nodal deformation. I&#8217;m curious if this is result of an error in my code or if I am not outputting the correct information when I run the simulation?&lt;\/p&gt;&lt;p&gt;Here is the code:&lt;\/p&gt;&lt;p&gt;&lt;span style=&#8221;font-size: 12pt;&#8221;&gt;\/post1&lt;\/span&gt;&lt;br&gt;&lt;span style=&#8221;font-size: 12pt;&#8221;&gt;file,file,rst !select result file&nbsp;&lt;\/span&gt;&lt;\/p&gt;&lt;p&gt;&lt;span style=&#8221;font-size: 12pt;&#8221;&gt;SET, LAST&lt;\/span&gt;&lt;\/p&gt;&lt;p&gt;&lt;span style=&#8221;font-size: 12pt;&#8221;&gt;!
