Hi all, I updated PETSc to 3.22.1, and now my code run with the following error message. Any idea this may happen? In the entire code, VecGetArray() are used in the following places: void PETScApp::setupPETScIC() { PetscScalar *uu; VecGetArray(u, &uu); _sim->setupPETScIC(uu); VecRestoreArray(u, &uu); } PetscErrorCode snesFormFunction(SNES /*snes*/, Vec u, Vec f, void * appCtx) { PETScApp * petscApp = (PETScApp *)appCtx; // zero out residuals VecZeroEntries(petscApp->res_tran); VecZeroEntries(petscApp->res_spatial); // get vectors PetscScalar *uu, *res_tran, *res_spatial; VecGetArray(u, &uu); VecGetArray(petscApp->res_tran, &res_tran); VecGetArray(petscApp->res_spatial, &res_spatial); // use the most updated solution vector to update solution, to compute RHS and transient residuals petscApp->_sim->updateSolutions(uu); petscApp->_sim->updateAuxVariables(); petscApp->_sim->computeTranRes(res_tran); petscApp->_sim->computeSpatialRes(res_spatial); // restore vectors VecRestoreArray(u, &uu); VecRestoreArray(petscApp->res_tran, &res_tran); VecRestoreArray(petscApp->res_spatial, &res_spatial); // assemble final residuals: f = transient + spatial VecWAXPY(f, 1.0, petscApp->res_tran, petscApp->res_spatial); PetscFunctionReturn(PETSC_SUCCESS); } PS: PETSc is available provided by moose env. -Ling Time Step 1, time = 0.1, dt = 0.1 [0]PETSC ERROR: --------------------- Error Message -------------------------------------------------------------- [0]PETSC ERROR: Object is in wrong state [0]PETSC ERROR: Vector 'Vec_0x84000002_0' (argument #1) was locked for read-only access in unknown_function() at unknown file:0 (line numbers only accurate to function begin) [0]PETSC ERROR: WARNING!
