TSBasicSymplecticRegister#

register a basic symplectic integration scheme by providing the coefficients.

Synopsis#

#include "petscts.h"   
PetscErrorCode TSBasicSymplecticRegister(TSRosWType name, PetscInt order, PetscInt s, PetscReal c[], PetscReal d[])

Not Collective, but the same schemes should be registered on all processes on which they will be used

Input Parameters#

  • name - identifier for method

  • order - approximation order of method

  • s - number of stages, this is the dimension of the matrices below

  • c - coefficients for updating generalized position (dimension s)

  • d - coefficients for updating generalized momentum (dimension s)

Note#

Several symplectic methods are provided, this function is only needed to create new methods.
