<p class="MsoNormal"><span lang="EN-US">I am a PhD student looking to solve a Laplacian on a 3D domain which consists of a volume with ellipsoid “holes” in it. I am a newcomer to PETSc, and would like advice on how to begin to write this code. I have studied
the examples, and example no.12 in SNES seems to share some of the </span>same characteristics that I need.
<o:p></o:p></p>
<p class="MsoNormal">I have also looked at the mail archives, but unfortunately couldn’t find too much on this problem – it may be that I lack the background to understand it properly.
<o:p></o:p></p>
<p class="MsoNormal">Thanks in advance for any advice, it is much appreciated.<o:p></o:p></p>
<p class="MsoNormal">(As an aside, I am also planning to run this in Rust using the PETSc bindings – if anyone has any experience with this it would be interesting to hear from you as well!)<o:p></o:p></p>
