<p>Hi.</p>
<p><br>
</p>
<p>I'm trying to read a mesh of higher element order, in this example a mesh consisting of 10-node tetrahedral elements, from gmsh, into PETSC. But It looks like the mesh is not properly being loaded and converted into a DMPlex. gmsh tells me it has generated
a mesh with 7087 nodes, but when I view my dm object it tells me it has 1081 0-cells. This is the printout I get</p>

<p>To replicate the error try generating a mesh according to</p>

<p>setting the element order to 2, and then loading the mesh using</p>
<p><br>
</p>
<p>DMPlexCreateGmshFromFile</p>
<p><br>
</p>
<p>I don't have any issues when i set the element order to 1.<br>

<p>Thanks in advance,</p>
