Existing deterministic simulations can be edited from the Study Tree or from the Alternative Simulation Manager. To edit the existing simulation from the Study Tree, right-click on the simulation of interest and select Edit Simulation from the shortcut menu. Alternatively, from the Alternative and Simulation Manager (opened from the WAT Tools toolbar by clicking 
), from the table right-click on the simulation of interest and select Edit Simulation from the shortcut menu.
Either option opens the Simulation Editor for the deterministic simulation (e.g., Deterministic).
From the Simulation Editor users can edit the Description field, the Program Order, the selected model Alternative(s), the Simulation Time Window, and/or Time Window Adjustment for each model alternative.
