So i should use petsc-dev ? I will try that. <br><br>I there any way i can have access to submesh? Consider a this scenario.<br>I have a two dimensional mesh in a rectangle with a uniform deltaX and deltaY gridding. Is there any way i can get submesh at say x = (i-1)*deltaX where say i = 1 to N. The dofs on the submesh will should be mapped to dofs on the original mesh. The submesh in this case will be a 1D mesh along y-axis. <br>
<br>I can create each DM with input celllist and create maps after that but i am wondering if this can be done via DMgetsubDM kind of call ?<br><br>Thanks<br>Reddy <br><br><div class="gmail_quote">On Sun, Mar 3, 2013 at 2:11 PM, Matthew Knepley <span dir="ltr"><<a href="mailto:knepley@gmail.com" target="_blank">knepley@gmail.com</a>></span> wrote:<br>
