The Close command on the File menu will close all windows displaying the active simulation. If the active simulation has been modified in any way, Gas Man® will give you the opportunity to save (or re-save) your simulation before you close it. Closing a simulation without saving will discard all changes made since the last time it was saved.
You can also close a simulation by using the Close icon on the simulation's window.
