You should have the 300-nodes demo version of NASTRAN, that´s why it is limited... I think it is difficult to find something cheap in this matter,...have you tried with PATRAN?

The fea software you need depends on how sophisticated you want your analysis to be.<br><br>For example, you are probably looking to use the panels as floor boards.&nbsp;&nbsp;If this is the case you can analyse them for simple shear and bending using classical analysis techniques.<br><br>FEM of composite panels can be complex, and largely unneccessary in straight forward applications like home built aircraft.<br><br>If you need help with analysis, let me know. <p>Nigel Waterhouse<br><a href=mailto:n_a_waterhouse@hotmail.com>n_a_waterhouse@hotmail.com</a><br><a href= > </a><br>A licensed aircraft mechanic and graduate engineer.
