<p>Hi,</p>
<p><br>
</p>
<p>I am running a FEM program using PETSc. In the beginning, the mesh is partitioned in gmsh, and we read the partitioned mesh using our own reader.</p>
<p><br>
</p>
<p>Now my question is: How can I get a global to local indices mapping? and do I need to renumber the indices after I read the partitioned mesh?</p>
<p><br>
</p>
<p>From my understanding, the rows handled by each processor should be consecutive, but the indices of nodes which I directly read from a gmsh file are not. Is this an issue?</p>
<p><br>
</p>
<p>Best,</p>
<p><br>
