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