A note on # of Time Steps
For steady state simulations, enough time steps must be included to reach steady state conditions.  Otherwise, the results will be invalid.  To determine if convergence has been reached.  Store near zone values.  Look at the near zone values to determine if Steady State has been reached.
For transient simulation, more time steps will allow larger FFT transforms.  This will give plots more data points, giving smoother graphs.
