Hello, I am unsure why the program crashes even while running the code serially
petscErr = MatCreate(mesh.comm().get(), &par_G); petscErr = MatSetType(par_G, MATMPIAIJ); petscErr = MatSetSizes(par_G, local_num_rows, local_num_cols, total_num_rows, total_num_cols); PetscInt d_nz = 2; PetscInt o_nz = 2; petscErr = MatMPIAIJSetPreallocation(par_G, d_nz, NULL, o_nz, NULL); petscErr = VecCreateMPI(mesh.comm().get(),local_num_cols,total_num_cols,&par_xcoord); petscErr = VecDuplicate(par_xcoord,&par_xvec); petscErr = MatMult(par_G, par_xcoord, par_xvec); [0]PETSC ERROR: --------------------- Error Message -------------------------------------------------------------- [0]PETSC ERROR: Nonconforming object sizes [0]PETSC ERROR: Mat mat,Vec y: global dim 40 25 [0]PETSC ERROR: WARNING!
