TSAdaptSetStepLimits#

Set the minimum and maximum step sizes to be considered by the time step controller

Synopsis#

#include "petscts.h" 
PetscErrorCode TSAdaptSetStepLimits(TSAdapt adapt, PetscReal hmin, PetscReal hmax)

Logically Collective

Input Parameters#

  • adapt - time step adaptivity context, usually gotten with TSGetAdapt()

  • hmin - minimum time step

  • hmax - maximum time step

Options Database Keys#

  • -ts_adapt_dt_min - to set minimum time step

  • -ts_adapt_dt_max - to set maximum time step

Note#

Use PETSC_CURRENT to keep the current value for either parameter

Fortran Note#

Use PETSC_CURRENT_REAL
