<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>
