SNESNormSchedule

Frequency with which the norm is computed

Synopsis

typedef enum {SNES_NORM_DEFAULT            = -1,
              SNES_NORM_NONE               =  0,
              SNES_NORM_ALWAYS             =  1,
              SNES_NORM_INITIAL_ONLY       =  2,
              SNES_NORM_FINAL_ONLY         =  3,
              SNES_NORM_INITIAL_FINAL_ONLY =  4} SNESNormSchedule;

Support for these is highly dependent on the solver.

Notes

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