DMMonitorSet#

Sets an additional monitor 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, PetscCtxDestroyFn *monitordestroy)

Logically Collective

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), see PetscCtxDestroyFn for the calling sequence

Options Database Key#

-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.

Note#

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

Fortran Note#

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

Developer Note#

This API has a generic name but seems specific to a very particular aspect of the use of DM
