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