Hi Barry, I have a quick question on PC Galerking as I am trying to do the same thing reported in this post: https://urldefense.us/v3/__https://lists.mcs.anl.gov/pipermail/petsc-users/2017-June/032934.html__;!!G_uCfscf7eWS!bQ0VYCU_TuGCB-803OHYrdOURUwlOpEAp1j5pu1v1Kh6eUgPPdRF_wkiLfrW342u8LNZ4mpCiqz4OxsAOywju5ZUi9bIZUs$
This my command line: mpirun -np 4 flubio_coupled* -UPeqn_pc_type composite -UPeqn_pc_composite_pcs galerkin,bjacobi -UPeqn_sub_0_galerkin_ksp_type preonly -UPeqn_sub_0_galerkin_pc_type none* And this is the error: [0]PETSC ERROR: --------------------- Error Message -------------------------------------------------------------- [0]PETSC ERROR: Object is in wrong state [0]PETSC ERROR: Must set operator of PCGALERKIN KSP with PCGalerkinGetKSP()/KSPSetOperators() Do I need to set something for PCGALERKING in my code to make it work from command line? Thank you!
