Thanks for your suggestions. Here's the outcome:<br>
<br>
1) without the "if type=nest" protection, I get a "Cannot<br>
locate function MatNestSetSubMats_C" error when using<br>
type mpiaij, see below.<br></blockquote><div><br></div><div>That is a bug. It should be using PetscTryMethod() there, not PetscUseMethod(). We will fix it.

2) with the isg in a proper array, I get the same "Invalid<br>
Pointer to Object" error, see below.<br></blockquote><div><br></div><div>Can you send a small example that we can run? It obviously should work this way.</div><div><br></div><div> Thanks,</div><div><br></div><div> Matt</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
