Basically, the value at cell centroid needs to be mapped to vertex (or vice versa) through interpolation/extrapolation for coupling of two codes. Does petsc function provide this kind of mapping between cell centroid and vertex? The grids for the two codes can be overlapped. I was trying to find some FEM infrastructures in petsc, but so far havent found that kind of functionality. Can I get any comments on that?</div><div><br></div><div>Thanks, </div><div>Mike</div><div><br></div></div>
