Sets an ADDITIONAL function that is to be used after a solve to monitor discretization performance.

Synopsis

#include "petscdm.h"          
#include "petscdmlabel.h"     
#include "petscds.h"     
PetscErrorCode DMMonitorSet(DM dm, PetscErrorCode (*f)(DM, void *), void *mctx, PetscErrorCode (*monitordestroy)(void**))
Logically Collective on DM

Input Parameters

DM - the DM
f - the monitor function
mctx - [optional] user-defined context for private data for the monitor routine (use NULL if no context is desired)
monitordestroy - [optional] routine that frees monitor context (may be NULL)

Options Database Keys

-dm_monitor_cancel -cancels all monitors that have been hardwired into a code by calls to DMMonitorSet(), but does not cancel those set via the options database.

Notes

Several different monitoring routines may be set by calling DMMonitorSet() multiple times; all will be called in the order in which they were set.

Fortran Notes

Only a single monitor function can be set for each DM object
