TSMPRKRegister#
register a TSMPRK scheme by providing the entries in the Butcher tableau
Synopsis#
#include "petscts.h"   
PetscErrorCode TSMPRKRegister(TSMPRKType name, PetscInt order, PetscInt sbase, PetscInt ratio1, PetscInt ratio2, const PetscReal Asb[], const PetscReal bsb[], const PetscReal csb[], const PetscInt rsb[], const PetscReal Amb[], const PetscReal bmb[], const PetscReal cmb[], const PetscInt rmb[], const PetscReal Af[], const PetscReal bf[], const PetscReal cf[])
Not Collective, but the same schemes should be registered on all processes on which they will be used, No Fortran Support
Input Parameters#
- name - identifier for method 
- order - approximation order of method 
- sbase - number of stages in the base methods 
- ratio1 - stepsize ratio at 1st level (e.g. slow/medium) 
- ratio2 - stepsize ratio at 2nd level (e.g. medium/fast) 
- Asb - stage coefficients for slow components(dimension s*s, row-major) 
- bsb - step completion table for slow components(dimension s) 
- csb - abscissa for slow components(dimension s) 
- rsb - array of flags for repeated stages for slow components (dimension s) 
- Amb - stage coefficients for medium components(dimension s*s, row-major) 
- bmb - step completion table for medium components(dimension s) 
- cmb - abscissa for medium components(dimension s) 
- rmb - array of flags for repeated stages for medium components (dimension s) 
- Af - stage coefficients for fast components(dimension s*s, row-major) 
- bf - step completion table for fast components(dimension s) 
- cf - abscissa for fast components(dimension s) 
Note#
Several TSMPRK methods are provided, this function is only needed to create new methods.
