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;
Many br

Support for these is highly dependent on the solver. Many br

Notes

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