We've created a free Demo Version of Multi-Sim so that you can
give it a test-drive. Depending on your application, you may
find the Demo Version is all you need!
The Demo Version's features are:
- It simulates a single aircraft, the Cessna 172.
- The program uses the same six degree-of-freedom, non-linear
dynamic modeling algorithms as our standard versions, producing
the same high-fidelity predictions.
- The aircraft flies in a flat-Earth spatial model, with
no ground reaction.
- The atmosphere is simulated using an International Standard
- The 172's engine varies in maximum power with altitude.
- There are no sensor models. The returned aircraft data
is "truth data".
- Control inputs go directly to the control surfaces (the
172 has no actuators) and change instantaneously.
- The simulation will run only one instance at a time.
- The program runs for 30 minutes, then must be restarted.

- Create a folder where you'll save the system. You can do
this in your user folder: "c:\users\you\multi-sim", or
in your computer's program folder:
"c:\program files (x86)\multi-sim".
- Extract the folders and files into the folder you
- If you created the new folder in the "program files (x86)"
folder, make sure you have write permission set for it and
its sub-folders. Open the Command Prompt (press the start
button and then enter "cmd"). Enter the command:
ATTRIB -r /s /d "C:\PROGRAM FILES (X86)\MULTI-SIM\*.*"
- When you first start Multi-Sim, Windows will ask you whether
it should allow Multi-Sim to access your private network and
the Internet. Check both boxes and then click "ok".
- The simulation, stored in the main folder, is called
"Multi-Sim.exe" and the two clients, stored in the "C" and
"Forth" folders, are called "Open-Loop Cab.exe".
Double-click on the programs to start them.
- Delete the folder where you saved Multi-Sim.
- That's it!
