The necessary files are located in the "Models/Tug_of_War" folder of the OpenSim Resources directory (by default, C:/Users/<username>/Documents/OpenSim/4.1). Locate the model file 'Tug_of_War_Millard.osim', the controls file 'Tug_of_War_Millard_controls.xml' , and the initial states file 'Tug_of_War_Millard_initial_states.sto' and copy them into your working directory. Copy the model and save it with the filename Tug_of_War_Millard_Iso.osim.

D. Design your best Tug-of-War competitor
You win the competition by getting the center of the block onto your side of the arena at the end of a 1.0-second simulation. For this competition, start with a copy of the original Tug_of_War_Millard.osim model file.
The design variables that you can modify to create your competitor are:
...
The initial activation will be 0.01 and the initial fiber length will be determined by the equilibrium condition. To match these conditions in your testing, make sure your muscle's default_activation is 0.01 and enable "Solve for equilibrium for actuator states" when using the ForwardTool.
Before you begin creating muscles, write down your conceptual strategy for building the best muscle possible.
