AFAICT the actual problem has been fixed, https://github.com/libMesh/libmesh/pull/976/files
except that the error report could be more informative. However, this would probably work too for anyone reading archives, http://www.mcs.anl.gov/petsc/petsc-current/docs/manualpages/KSP/KSP_DIVERGED_PCSETUP_FAILED.html Notes: Run with -ksp_error_if_not_converged to stop the program when the error is detected and print an error message with details. once you have some idea where to look. I changed my data a bit and not getting the problem now.

We really should use the PETSc API here to print some sane string from within libMesh, though, not just "unrecognized". A PR would be appreciated. Thanks. I guess just printing the unrecognized code would make it possible for the user to look it up and that is really all I need now. Although if you print general error messages from insdie the code that should not fail, But libmesh doesn't throw an error/fail when PetscLinearSolver<T>::get_converged_reason() gets an unrecognized reason, it just prints a message to std::err. Is it your code that is throwing the error? -- John ---------------------------------- No one is throwing - that was my point. If you do what you do now just adding the file/line info and unrecognized value to the output would help. If the value is reasonable for the PETSc I'm linked to that is one thing, if it is xCDCDCDCD that is another problem :) Thanks. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Libmesh-users mailing list Libmesh-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libmesh-users ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Libmesh-users mailing list Libmesh-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libmesh-users
