[Facets-devel] PETSC ERROR

Should we make optfile in PetscIntialize(optfile) optional?

Current code is:

PetscIntialize("file") -> PetscOptionsInsert(optfile) ->

i.e it gives error if the "optfile" is not found.

Should the code be changed to use:

Alternatives would be to expose the flag - a bit higher [i.e use
PetscOptionsInsert(file,flg)] or expose it further up to
PetscIntialize(optfile,flg). But changing PetscIntialize() might not
be desireable.

I'm inclined to use:
PetscIntialize("file") -> PetscOptionsInsert(optfile,PETSC_FALSE) ->
