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 ts, PetscInt steps, PetscReal time, Vec u, void *ctx), void *mctx, PetscCtxDestroyFn *mdestroy)

Logically Collective

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)

• mdestroy - [optional] routine that frees monitor context (may be NULL), see PetscCtxDestroyFn for the calling sequence

Calling sequence of monitor

• 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

• ctx - [optional] monitoring context

Note

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
