Save Command (File menu)

Use this command to save the active simulation and its current name and directory location. The first time you save a simulation, the "Save As" window appears so you can name your simulation.

On subsequent "saves" of the file, the Save command is automatic. That is, There is no dialog. It saves the file with the same name and properties in the same location. If you wish to change the name or location of an existing simulation before saving it, choose the Save As command.
