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
