TSMonitorSet

Sets an ADDITIONAL function that is to be used at every timestep to display the iteration's progress.

Synopsis

#include "petscts.h"  
PetscErrorCode  TSMonitorSet(TS ts,PetscErrorCode (*monitor)(TS,PetscInt,PetscReal,Vec,void*),void *mctx,PetscErrorCode (*mdestroy)(void**))

Logically Collective on TS

Input Parameters

	ts	- the TS context obtained from TSCreate()
	monitor	- monitoring routine
	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)

Calling sequence of monitor

   PetscErrorCode monitor(TS ts,PetscInt steps,PetscReal time,Vec u,void *mctx)

	ts	- the TS context
	steps	- iteration number (after the final time step the monitor routine may be called with a step of -1, this indicates the solution has been interpolated to this time)
	time	- current time
	u	- current iterate
	mctx	- [optional] monitoring context

Notes

This routine adds an additional monitor to the list of monitors that already has been loaded.

Fortran Notes

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