 If you don't want to complie the model on your own computer, you should be able to use the provided executable (samsim.x).

-Now you can simply run samsim by running the executable file. Windows user will need to run it from their Linux 
-sub-system which is activated by typing into the console :

-After Samsim has finished you can plot the output as described below :)
