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 on TS Many br

Input Arguments

ts - time stepping context Many br
wnormtype - norm type, either NORM_2 or NORM_INFINITY Many br
order - optional, desired order for the error evaluation or PETSC_DECIDE Many br

Output Arguments

order - optional, the actual order of the error evaluation Many br
wlte - the weighted local truncation error norm Many br

Many br

Notes

If the timestepper cannot evaluate the error in a particular step Many br(eg. in the first step or restart steps after event handling), Many brthis routine returns wlte=-1.0 . Many br
