PETSc version 3.15.5
TSErrorWeightedENorm
compute a weighted error norm based on supplied absolute and relative tolerances 
Synopsis
#include "petscts.h"  
PetscErrorCode TSErrorWeightedENorm(TS ts,Vec E,Vec U,Vec Y,NormType wnormtype,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 | 
|  | wnormtype | - norm type, either NORM_2 or NORM_INFINITY | 
Output Arguments
|  | norm | - weighted norm, a value of 1.0 achieves a balance between absolute and relative tolerances | 
|  | norma | - weighted norm, a value of 1.0 means that the error meets the absolute tolerance set by the user | 
|  | normr | - weighted norm, a value of 1.0 means that the error meets the relative tolerance set by the user | 
Options Database Keys
|  | -ts_adapt_wnormtype <wnormtype> | - 2, INFINITY |
