TSAlpha2GetParams#
gets the algorithmic parameters for TSALPHA2
Synopsis#
#include "petscts.h"
PetscErrorCode TSAlpha2GetParams(TS ts, PetscReal *alpha_m, PetscReal *alpha_f, PetscReal *gamma, PetscReal *beta)
Not Collective
Input Parameter#
ts - timestepping context
Output Parameters#
alpha_m - algorithmic parameter
alpha_f - algorithmic parameter
gamma - algorithmic parameter
beta - algorithmic parameter
Note#
Use of this function is normally only required to hack TSALPHA2 to use a modified
integration scheme. Users should call TSAlpha2SetRadius() to set the high-frequency damping
(i.e. spectral radius of the method) in order so select optimal values for these parameters.
