compute a weighted 2 error norm based on supplied absolute and relative tolerances

Synopsis

#include "petscts.h"  
PetscErrorCode TSErrorWeightedENorm2(TS ts,Vec E,Vec U,Vec Y,PetscReal *norm,PetscReal *norma,PetscReal *normr)
Collective on TS

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
