TSErrorWeightedENormInfinity
compute a weighted infinity error norm based on supplied absolute and relative tolerances Collective on TS
Synopsis
#include "petscts.h"
PetscErrorCode TSErrorWeightedENormInfinity(TS ts,Vec E,Vec U,Vec Y,PetscReal *norm,PetscReal *norma,PetscReal *normr)
Input Arguments
| ts | - time stepping context
|
| E | - error vector
|
| U | - state vector, usually ts->vec_sol
|
| Y | - state vector, previous time step
|
Output Arguments
norm -weighted norm, a value of 1.0 means that the error matches the tolerances
norma -weighted norm based on the absolute tolerance, a value of 1.0 means that the error matches the tolerances
normr -weighted norm based on the relative tolerance, a value of 1.0 means that the error matches the tolerances
