[petsc-users] Not displaying petsc options with -help

[Jacob Faibussowitsch]

Not directly, but you can use PetscOptionsHasHelp() to query whether the user runs with “-help”, print all of your available options and exit early. So you might do:

PetscOptionsBegin();
< your options list here >
PetscOptionsEnd();
PetscOptionsHasHelp(NULL, &set);
If (set) PetscFinalize();

You’ll still get the header with the basic PetscOptions but it shouldn’t print all the other options.

When running the application with “-help” option all the application and PETSc options get displayed. Is there a way to suppress displaying PETSc options, but only display the application options.
