<p>Hi Matthew,</p>
<p>That is ok. May I ask you one more question?</p>
<p>Sorry. I just start to learn how to use DMPLex. If I have an msh file including the triangular elements (t3). After I use DMPlex to read this mesh, how can I know the element type (actually which is t3) by using the functions inside DMPlex?</p>
<p>Best,</p>
<p>Jian</p>

<p>Hi Matthew,</p>
<p>Thanks for your answer. I just looked at the pestc4py 3.11.0 (I think it is the newest one). </p>
<p>Actually, I did not find DMPlexGetClosure function in the DMPlex.pyx, also not in DM.pyx.</p>

<p>Hi Jed,</p>
<p>Thank you very much. I tried to use DMPlexGetCone, but the output is the edge ids, not the vertice ids. For the function <span>DMPlexGetClosureIndices, I can not find it in petsc4py. Do you know any alternative ways to solve this?</span></p>

<div>DMPlexGetClosure() should be in petsc4py. It also returns orientations, which you can just filter out.</div>
