Simulink Scope Plot Running Faster Than Simulation

Hi,

I have an issue where I'm trying to hook up a scope to plot the change in joint angles of my SimMechanics system and the scope runs much faster than the simulation does. I have the simulation length set to 50s and the time steps at 0.01s, yet the scope plots out all the angles within 20 seconds. Is there some configuration change I have to make to sync it with the simulation or is there something else that I'm missing here?

Thanks!

Simulink does not run in real-time. The Simulink model will execute one step of your model, and then immediately move on to the next time step (including plotting scopes if appropriate). Depending on the complexity of your model, this may be slower or faster than wall-clock time.

You could get something approximating wall clock time by using something like this: http://www.mathworks.com/matlabcentral/fileexchange/29107-real-time-pacer-for-simulink.

That does exactly what I need. Thanks!
