I am using DMPlex for a code with written in Fortran in 2D and 3D. There were two questions.
- As a follow up of the previous inquiry: https://www.mail-archive.com/petsc-users@mcs.anl.gov/msg43856.html Is the local-to-local halo exchange available in Fortran now or still pending? Currently local-to-global and global-to-local communication are used since local-to-local has not been allowed for Fortran. - One code solves discretized equations at each vertex, and another code I want to couple physics is solving equations at each cell centroid. 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? Thanks, Mike
