https://communities.bentley.com/products/geotech-analysis/f/forum/204740/unable-to-assign-platemat-properties-in-commands-runnerHello, I am unable to assign properties to my plate by the commands runner. If I run only that : _platemat &quot;MaterialName&quot; &quot;Paroi gauche&quot; &quot;MaterialNumber&quot; 0 &quot; IsIsotropic&quot; True &quot;PreventPunching&quot; True &quot;EA&quot; 20000000 &quot;EI&quot; 1666667 &quot;nu&quot; 0.2 &quot;w&quot; 0.15 en-USTelligent Community 12https://communities.bentley.com/thread/615994?ContentTypeID=1Fri, 23 Oct 2020 08:31:02 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:b5f17d10-266b-4f84-873e-94dd49e1f965Stefanos Papavasileiou<p>Dear Tomasz,</p> <p>Similarly to what is happening with soil materials, the plate also requires the definition of <em>Gref</em> instead. The minimum required parameters for a plate are the <em>Gref</em> and <em>d</em>.</p> <p>You can compute the Gref using the known equations:<br /><em>Gref = E / (2 * (1 + nu))</em></p> <p>where:<br /><em><span style="font-family:inherit;">E = EA / d<br /></span>d = sqrt(12 * EI / EA)</em></p> <p>For instance, for the case you present you can run the following:<br /><em>platemat (&quot;MaterialName&quot; &quot;Paroi gauche&quot;) (&quot;Gref&quot; 8333332.500000126) (&quot;d&quot; 1.000000099999995) (&quot;nu&quot; 0.2) (&quot;EA&quot; 20000000) (&quot;EA2&quot; 20000000) (&quot;EI&quot; 1666667) (&quot;w&quot; 0.15) (&quot;PreventPunching&quot; True)</em></p> <p>If you have more questions, please feel free to gather them and submit a service request.&nbsp;Then, one of our support engineers can help you in detail:<br /> <a href="https://apps.bentley.com/srmanager/ProductSupport">https://apps.bentley.com/srmanager/ProductSupport</a></p><div style="clear:both;"></div>
