TSMonitorLGSolution#

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

Synopsis#

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

Collective

Input Parameters#

  • ts - the TS context

  • step - current time-step

  • ptime - current time

  • u - current solution

  • dctx - the TSMonitorLGCtx object that contains all the options for the monitoring, this is created with TSMonitorLGCtxCreate()

Options Database Key#

  • -ts_monitor_lg_solution_variables - enable monitor of lg solution variables

Notes#

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

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.
