<div><br></div><div>Can this example be used with a DM object created from an unstructured exodusII mesh, DMMeshCreateExodus, And the FEM assembly done on GPU ?</div></div></blockquote><div><br></div><div>1) I have pushed many more tests for it now. They can be run using the Python build system</div>
<div><br></div><div> ./config/builder2.py check src/snes/examples/tutorials/ex52.c</div><div><br></div><div> in fact, you can build any set of files this way.</div><div><br></div><div>2) The Exodus creation has to be converted to DMComplex from DMMesh. That should not take me very long. Blaise maintains that</div>
<div> so maybe there will be help :) You will just replace DMComplexCreateBoxMesh() with DMComplexCreateExodus(). If you request</div><div> it, I will bump it up the list.</div></div></blockquote><div><br></div><div>DMMeshCreateExodusNG is much more flexible than DMMeshCreateExodus in that it can read meshes with multiple element types and should have a much lower memory footprint. The code should be fairly easy to read. you can email me directly if you have specific questions. I had looked at creating a DMComplex and it did not look too difficult, as long as interpolation is not needed. I have plans to write DMComplexCreateExodus, but haven't had time too so far. Updating the Vec viewers and readers may be a bit more involved. In perfect world, one would write an EXODUS viewer following the lines of the VTK and HDF5 ones. </div><div><br></div><div>Blaise</div><div><br></div><br><blockquote type="cite"><div class="gmail_quote"><div><br></div><div>Let me know if you can run the tests.</div>
