TSSundialsSetMaxl#

Sets the dimension of the Krylov space used by GMRES in the linear solver in TSSUNDIALS. TSSUNDIALS DOES NOT use restarted GMRES so this is the maximum number of GMRES steps that will be used.

Synopsis#

#include "petscts.h" 
PetscErrorCode TSSundialsSetMaxl(TS ts, PetscInt maxl)

Logically Collective

Input Parameters#

  • ts - the time-step context

  • maxl - number of direction vectors (the dimension of Krylov subspace).
