PetscErrorCode SNESMonitorDefault(SNES snes, PetscInt its, PetscReal fgnorm, PetscViewerAndFormat *vf)
Collective
Input Parameters#
- snes - the - SNEScontext
- its - iteration number 
- fgnorm - 2-norm of residual 
- vf - viewer and format structure 
Options Database Key#
- -snes_monitor - use this function to monitor the convergence of the nonlinear solver 
Notes#
Prints the residual norm at each iteration.
This is not called directly by users, rather one calls SNESMonitorSet(), with this function as an argument, to cause the monitor
to be used during the SNES solve.
