<p>Hello,</p>
<p><br>
</p>
<p>I have made a model of 3D Magnetic Circuit. Iron core is modeled as cylinder and coil with a airgap are modeled as cylinders and generated using BoleanDifference. I have merged the geometry with Magnestotatics template and run into some errors:</p>
<p><br>
</p>
<p>error : getdp - null determinant in 'changeofcoord_form2'</p>
<p><br>
</p>
<p>and</p>
<p><br>
</p>
<p>Error : Invalid boundary mesh (segment-facet intersection) on surface 4 surface 5, intersection (0.018256,-0.00346128,0.0060024)<br>
</p>
<p>Error : No tetrahedra in region 3 4 35 61 87 113 139 165 300026 <br>
</p>
<p><br>
</p>
<p>Please find the code of Geometry:</p>
<p><br>
</p>
<p>What could be the problems? <br>
</p>
<p><br>
</p>
<p><br>
</p>
<p>Kind regards,</p>
