TSSundialsSetTolerance#

Sets the absolute and relative tolerance used by TSSUNDIALS for error control.

Synopsis#

#include "petscts.h" 
PetscErrorCode TSSundialsSetTolerance(TS ts, PetscReal aabs, PetscReal rel)

Logically Collective

Input Parameters#

  • ts - the time-step context

  • aabs - the absolute tolerance

  • rel - the relative tolerance

See the CVODE/SUNDIALS users manual for exact details on these parameters. Essentially these regulate the size of the error for a SINGLE timestep.
