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 Many br
Input Parameter
ts -timestepping context Many br
Output Parameters
| \alpha_m | - algorithmic parameter Many br |
| \alpha_f | - algorithmic parameter Many br |
| \gamma | - algorithmic parameter Many br |
Note
Use of this function is normally only required to hack TSALPHA to Many bruse a modified integration scheme. Users should call Many brTSAlphaSetRadius() to set the high-frequency damping (i.e. spectral Many brradius of the method) in order so select optimal values for these Many brparameters. Many br
