The PHAST Time Control dialog box is used to specify how the time step size varies period-by-period during the simulation. The PHAST Time Control dialog box is displayed by selecting Model|PHAST Time Control… The user species a Time step length and the Ending time when the time step length changes to another value or the simulation ends. The times entered in the PHAST Time Control dialog box do not need to be the same as the times entered in other parts of the model. ModelMuse synthesizes all the times throughout the model and combines them to create the PHAST input file.
Start time allows the calculations to begin at a time other than zero. This feature is useful for restart runs from the end of a previous calculation when chemical conditions were saved. See Restart in the PHAST Print Frequency dialog box.
