[petsc-users] Controlling ML

[John Fettig]

Is there any way to control ML other than the options database?  For
example, I want to set -pc_ml_maxNlevels 3, but there seems to be no
way to do it other than

a) the command line or
b) PetscOptionsSetValue("-pc_ml_maxNlevels","3");

This doesn't make it easy if you want to have more than one PCML.
