I&#8217;m doing this in mechanical with APDL command snippets.I have 5 command snippets and 6 time steps. The intention was to move the node for each step 2,3,4,5, and 6 using identical command snippets that work via step selection mode. I noticed that it is skipping steps 1\/2\/3\/4\/5 and just solving step 6 outputting only one time step. an example of one of the snippets is below:&lt;\/p&gt;&lt;p&gt;compression= -.741&lt;\/p&gt;&lt;p&gt;\/PREP7 csys,0 NSEL,S,,,GP2&lt;\/p&gt;<\/p>\n<pre><code>N,GP2,  NX(GP2), NY(GP2)+compression, NZ(GP2)\n<\/code><\/pre>\n<p>&lt;p&gt;ALLSEL,ALL&lt;\/p&gt;&lt;p&gt;\/Solution&lt;\/p&gt;&lt;p&gt;I think the issue is due to the solver trying to enter \/prep7 between each command snippet. is there anyway around this?
