<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">I already extended DMPlexBuildFromCellList_Parallel_Private to take elements with different shapes, then I realized the interpolation does not work when the

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">Regarding the interpolation, I also noticed that the memory requirement is huge if I load the whole mesh on one core and interpolate (I cannot interpolate a mesh
with 9M tets on a machine with 128GB of memory, it ran out of memory, I’ll try to run with petsc memory logs and send). is there anyways to interpolate the mesh after DMPlexdistribute? The code crashes if I move DMPlexInterpolate to after calling DMPlexdistribute.,
I guess what is needed is a DMPlexInterpolate on already distributed meshes.<o:p></o:p></span></p>
