Hey Matt,<br> In one piece of code I have, yes the call to DAGetInterpolation() does seem to cause a nasty crash.<br>It doesn't occur all the time, just with certain processor sizes (64) and certain mesh sizes (80x80x40). I was wondering if there was some pathological cases I did not know about. <br>
<br>I think I will have to write a stand alone test case to see if I can reproduce the error in a simpler code. <br>I don't think what I'm doing should cause a problem, but I'm not sure how best to debug the problem I have.<br>
<br>Any hints would be appreciated. :)<br><br>Cheers,<br> Dave<br><br><br><br><div class="gmail_quote">On Wed, Sep 23, 2009 at 2:33 PM, Matthew Knepley <span dir="ltr"><<a href="mailto:knepley@gmail.com">knepley@gmail.com</a>></span> wrote:<br>

If I now create a second DA using DARefine(), am I alays also able to obtain an interpolation operator between the two DA's via DAGetInterpolation()?<br>
<br>Under what circumstance will DAGetInterpolation() fail when used between DA's generated in this manner?<br><br>Cheers,<br><font color="#888888"> Dave<br><br>
