TSEvaluateWLTE#
Evaluate the weighted local truncation error norm at the end of a time step with a given order of accuracy.
Synopsis#
#include "petscts.h"
PetscErrorCode TSEvaluateWLTE(TS ts, NormType wnormtype, PetscInt *order, PetscReal *wlte)
Collective
Input Parameters#
ts - time stepping context
wnormtype - norm type, either
NORM_2orNORM_INFINITY
Input/Output Parameter#
order - optional, desired order for the error evaluation or
PETSC_DECIDE; on output, the actual order of the error evaluation
Output Parameter#
wlte - the weighted local truncation error norm
Note#
If the timestepper cannot evaluate the error in a particular step (eg. in the first step or restart steps after event handling), this routine returns wlte=-1.0 .
