Hello, i am using petsc in a single cpu setup where I have preassembled crs matrices that I wrap via PetSC's MatCreateSeqAIJWithArrays Functionality.
Now I manipulate the values of these matrices (wohtout changing the sparsity) without using petsc, When I now want to solve again I have to call PetscObjectStateIncrease((PetscObject)petsc_A); So that oetsc actually solves again (otherwise thinking nothing hs changed , This means I have to include the private header #include <petsc/private/petscimpl.h> Which makes a seamingless implementation of petsc into a cmake process more complicate (This guy has to be stated explicitly in the cmake process at the moment) I would like to resolve that by "going" around the private header, My first intuition was to increase the state by hand ((PetscObject)petsc_A_aux[the_sys])->state++; This is the definition of petscstateincrease in the header. This throws me an error: invalid use of incomplete type 'struct _p_PetscObject' compilation error. Is there any elegeant way around this? This is the first time I use the petsc mailing list so apologies for any beginners mistake I did in formatting or anything else. Best regards Franz Pichler
