TSGLLEAdaptChoose

Choose the next scheme and step size using a TSGLLEAdapt step-size and order controller

Synopsis

#include "petscts.h" 
PetscErrorCode TSGLLEAdaptChoose(TSGLLEAdapt adapt, PetscInt n, const PetscInt orders[], const PetscReal errors[], const PetscReal cost[], PetscInt cur, PetscReal h, PetscReal tleft, PetscInt *next_sc, PetscReal *next_h, PetscBool *finish)

Logically Collective

Input Parameters

• adapt - the TSGLLEAdapt context

• n - the number of candidate schemes

• orders - the orders of accuracy of the candidate schemes

• errors - the error estimates for each candidate scheme

• cost - the relative cost of each candidate scheme

• cur - the index of the currently active scheme

• h - the last step size that was taken

• tleft - the amount of remaining integration time

Output Parameters

• next_sc - the index of the scheme to use next

• next_h - the step size to take next

• finish - PETSC_TRUE if next_h was truncated to tleft because the end of the interval has been reached
