title: Abaqus: The following parts have some elements without any section assigned / Composite Layups
body: <p>I am building up composite layups and assigning them to element sets. When I do so as soon as I try to submit the job, Abaqus always gives me the error &quot;<strong>The following parts have some elements without any section assigned</strong>&quot;. There is not a single element without a material property, I do this by a script. As soon as I use a set which does not contain elements but a geometry Abaqus highlights the region green, but using geometry instead of element sets is not very suitable for me, because I am changing the properties of different elements. Also the region selection window opened by abaqus says &quot;Sets below may contain elements, cells, shell faces or wire edges&quot;, so it should be possible to use element sets right?</p>
  <p>I use the section assignment only for a small amount of elements, everything else is covered by composite layups.</p>
  <p>If needed I can share more details from my model, but as I am not sure where to look for any errors right now, I wont do that right now.</p>
  <p>Best regards and thanks for any advice!</p>
