<br>
I am new to PcFieldSplit.<br>
<br>
I have a matrix formed using MATMPIAIJ. Is it possible to use<br>
PCFIELDSPLIT operations in this type of matrix? Or does it have to be<br>
MATMPIBIJ or MATNEST format?<br></blockquote><div><br></div><div>Yes, you can split AIJ.</div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex">
If possible for MATMPIAIJ, could anybody provide me a simple example<br>
or few steps? Variables in the equations are displacement vector,<br>
