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.
