SNESNormSchedule#

Frequency with which the norm is computed during a nonliner solve

Synopsis#

Values#

Notes#

Support for these is highly dependent on the solver.

Some options limit the convergence tests that can be used.

The SNES_NORM_NONE option is most commonly used when the nonlinear solver is being used as a smoother, for example for SNESFAS

This is primarily used to turn off extra norm and function computation when the solvers are composed.
