<br>
I'm trying to create a distributed unstructured grid in PETSc, and have encountered the following error:<br>

I've created the DMPlex using `DMPlexCreateFromCellList`, added a default section and then called `DMPlexDistribute` to spread the grid points across all of the processors. You can see my test code at <a href="https://gist.github.com/ScottWales/2758b5ec96573c63e31a#file-petsc-test-c-L164" target="_blank">https://gist.github.com/<u></u>ScottWales/<u></u>2758b5ec96573c63e31a#file-<u></u>petsc-test-c-L164</a>. Have I missed a step in the grid setup?<br>
</blockquote><div><br></div><div>1) I have better checking in the 'master' branch, and we are about to release, so I recommend upgrading</div><div><br></div><div>2) You did not install with any mesh partitioner, so it freaked out. You need something like --download-chaco in configure.</div>
