In this simulation, it is verified that the statistically stationary state is reached by advancing the simulation from 0s to 0.1s in physical time i.e. using only 10,000 time steps with 1e-05s time step size with 20 inner iterations.When statistically stationary state is reached, statistics have to be collected by advancing the physical time from 0.1s to 0.2s. Use 10,000 time steps with 1e-05 time step size with 20 inner iterations. This is done as shown in the figure below. Check the Data Sampling for Time Statistics to start collecting the statistics. You will see the physical time for which the statistics have been collected across Time Sampled (s).

Collect the statistics for 0.05s as shown in the above figure. At this point save the project once again.
