Dear Petsc developers, I am trying to learn about the mesh refinement part. I tried to follow the instructions from the website, "Meshing for Subsurface Flows in PETSc, make -f ./gmakefile test globsearch="dm_impls_plex_tutorials-ex10_0", but it will run many tests and will not deliver "
DM <https://urldefense.us/v3/__https://petsc.org/release/manualpages/DM/DM/__;!!G_uCfscf7eWS!aTuEZNwxZ2ve5zOYEu5SDetjZlPcfc2PSiSmVCUcExxOERlForddvBHJQsxjVbpj-Nj9CGeSJ_mMEQGBDsVPPQ$ > Object: Mesh 1 MPI process type: plexMesh in 3 dimensions: Number of 0-cells per rank: 8 Number of 1-cells per rank: 14 (4) Number of 2-cells per rank: 9 (5) Number of 3-cells per rank: 2Labels: celltype: 6 strata with value/size (3 (4), 9 (2), 0 (8), 2 (4), 1 (10), 5 (5)) depth: 4 strata with value/size (0 (8), 1 (14), 2 (9), 3 (2)) marker: 1 strata with value/size (1 (24)) Face Sets: 1 strata with value/size (1 (12)) " While it is successful if I go to the directory for ex10 and make ex10 there and run with options there. DId I miss something? In addition, in order t view the mesh, I added the following lines to ex10.c, // Create HDF5 viewer PetscViewer viewer; const char *filename = "mesh.h5"; // Output file PetscViewerCreate(PETSC_COMM_WORLD, &viewer); PetscViewerSetType(viewer, PETSCVIEWERHDF5); PetscViewerFileSetMode(viewer, FILE_MODE_WRITE); PetscViewerFileSetName(viewer, filename); // Optionally set the name of the DM object if you are saving multiple meshes PetscObjectSetName((PetscObject)dm, "MyMeshName"); // Save DM to HDF5 file DMView(dm, viewer); This wil genearte a .h5 file. Then I run petsc-with-docs-3.21.1/petsc-3.21.1/lib/petsc/bin/petsc_gen_xdmf.py mesh.h5 This gave a .xml file. I tried to load this xml file into paraview using xdmf reader. But it was not successful. Did I miss something ? Thanks a lot, Xiaodong
