Dear all, <div> I still have the problem. >_<</div><div> I can not find the DMMG interface provided to change the RHS, mentioned by Dr. Smith. The only thing I have is DMMGSetKSP(). It is <span style="font-family: monospace; white-space: pre-wrap; background-color: rgb(255, 255, 255); font-size: medium;">DMMGSetKSP(dmmg,ComputeRHS,ComputeMatrix).</span>When I use it first time in this example, it calls both ComputeRHS and ComputeMatrix (I assert some print-out probes inside these two functions). However, If I use it again, it just does not call the new one; rather, it calls the old one. <br>
My code is attached. Could you please help me to fix this problem ^_^.</div><div><font face="monospace" size="3"><span style="white-space: pre-wrap;"><br>

In this example, i recalled the ComputeRHS.<div><br></div><div><font color="#888888">Alan</font><div><div></div><div><br><br><div class="gmail_quote">On Sun, Oct 2, 2011 at 5:22 PM, Jed Brown <span dir="ltr"><<a href="mailto:jedbrown@mcs.anl.gov" target="_blank">jedbrown@mcs.anl.gov</a>></span> wrote:<br>

BTW, what is the DMMG interface you are talking about? is it DMMGSetKSP()?</blockquote><div><br></div></div><div>Every object and function containing "DMMG" will be removed. (I don't think we've decided on a precise timeline, but don't write new code that uses DMMG.)</div>

At the 2nd time of using DMMGSetKSP() in the main function, it does not call the __function__ to compute the right hand side. >_< any suggestions on that?</blockquote>
