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, PetscErrorCode (*monitordestroy)(void **))
Logically Collective
Input Parameters#
- dm - the - DM
- f - the monitor function 
- mctx - [optional] user-defined context for private data for the monitor routine (use - NULLif no context is desired)
- monitordestroy - [optional] routine that frees monitor context (may be - NULL)
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
