If I use MatSetNearNullSpace on my matrix, the near nullspace isn’t propagated through to GAMG. If I attach the near nullspace to the IS used to define the splits, it still doesn’t propagate through to GAMG. Am I missing the correct way to do this?</div><div><br></div>Thanks,<br><div class="gmail_signature" ><div style="font-family:helvetica,arial;font-size:13px">Tristan Konolige</div></div></body></html>
