Hello,
You can change the frequency that you extract data from the simulation, but the Pulse simulations require a timestep that aligns with the nyquist frequency of the cardiovascular cycle. We have done some early testing of using a larger timestamp and we were able to double the timestep to 0.04 s and still achieve valid results. But currently the models cannot simulate a full hour at a time in a single timestep.
Here is a thread you may find helpful.
