TSMonitorLGError#

Monitors progress of the TS solvers by plotting each component of the error in a time based line graph

Synopsis#

#include "petscts.h"  
PetscErrorCode TSMonitorLGError(TS ts, PetscInt step, PetscReal ptime, Vec u, void *dummy)

Collective

Input Parameters#

  • ts - the TS context

  • step - current time-step

  • ptime - current time

  • u - current solution

  • dctx - TSMonitorLGCtx object created with TSMonitorLGCtxCreate()

Options Database Key#

  • -ts_monitor_lg_error - create a graphical monitor of error history

Notes#

Each process in a parallel run displays its component errors in a separate window

The user must provide the solution using TSSetSolutionFunction() to use this monitor.

This is not called directly by users, rather one calls TSMonitorSet(), with this function as an argument, to cause the monitor to be used during the TS integration.
