Hello, I have a problem running src/snes/tutorials/ex17.c in parallel, given the specific runtime options (these options are actually taken from the test example ex17_3d_q3_trig_elas).
*The serial version works fine:* ./ex17 -dm_plex_box_faces 1,1,1 -sol_type elas_trig -dm_plex_dim 3 -dm_plex_simplex 0 -displacement_petscspace_degree 3 -dm_refine 0 -convest_num_refine 1 -snes_convergence_estimate -snes_monitor *The parallel version fails:* mpirun -n 2 ./ex17 -dm_plex_box_faces 1,1,1 -sol_type elas_trig -dm_plex_dim 3 -dm_plex_simplex 0 -displacement_petscspace_degree 3 -dm_refine 0 -convest_num_refine 1 -snes_convergence_estimate -snes_monitor *with the error message (--with-debugging=1):* [0]PETSC ERROR: --------------------- Error Message -------------------------------------------------------------- [0]PETSC ERROR: Argument out of range [0]PETSC ERROR: Cell 0 has not been assigned a cell type [0]PETSC ERROR: WARNING!
