TSAdaptChoose

choose which method and step size to use for the next step

Synopsis

#include "petscts.h" 
PetscErrorCode TSAdaptChoose(TSAdapt adapt,TS ts,PetscReal h,PetscInt *next_sc,PetscReal *next_h,PetscBool *accept)
Collective on TSAdapt

Input Arguments

adapt - adaptive contoller
h - current step size

Output Arguments

next_sc - optional, scheme to use for the next step
next_h - step size to use for the next step
accept - PETSC_TRUE to accept the current step, PETSC_FALSE to repeat the current step with the new step size

Note

The input value of parameter accept is retained from the last time step, so it will be PETSC_FALSE if the step is being retried after an initial rejection.
