I have the example project "Train DDPG Agent to swing up and balance pendulum" working OK.

However, I have been unsuccessful in changing the simulation time.

There is a variable in the workspace called Tf, but modfying it does not seem to have any effect on the duration of the simulation.

What am I missing here ?

During training, each episode/simulation will last for Tf seconds at most. It may end sooner depending on the value of MaxStepsPerEpisode option in training options. It could also end sooner if the IsDone flag that is defined inside the Simulink model becomes 1.

If you are not training and running regular simulations with the "Play" button, the simulation will last for whatever value is specified next to the Play button.
