[petsc-users] How add arguments with PetscInitializeNoArguments()

[Barry Smith]

  With PETSc 3.7 you can do 

   PetscOptionsSetValue(NULL, "-log_summary",NULL);  etc
   PetscInitializeNoArguments();

   I certainly don't recommend it because it removes the flexibility of changing options at the command line, any time you want to change something you need to recompile.
