<div>Hello PETSc team:<br>
</div>
<div><br>
</div>
<div>I am trying to solve a PDE problem with high-order finite elements. The matrix is getting denser and my experience is that MUMPS just outperforms iterative solvers.</div>
<div><br>
</div>
<div>For certain problems, MUMPS just fail in the middle for no clear reason. I just wander if there is any suggestion to improve the robustness of MUMPS? Or in general, any suggestion for interative solver with very high-order finite elements?</div>
</div>

<div>What error message do you get when MUMPS fails? Out of memory, zero pivoting, or something?</div>
