Hi experts,
I have an unsteady and turbulent flow, I have established the data sampling box for time statistics. the time step Ee-5 and the number of time step 6000. I wish to perform a mean study of the results. I recorded the files every 50-time step. I do not know what I can put as a value in the sampling box for time statistics. I want to average after 2100 where the flow becomes stable. so an average between 2100 and 6000 Could you help me calculate the average speed over time for this transient simulation? Best regards, |

Most people put 1 so that that every time-step is sampled and included in the average. You can either keep the data sampling disabled and turn it on after time-step 2100 or if it is already on, reset the statistics at time-step 2100. Then solve until timestep 6000. |

Dear LuckyTran
Thank you very much for your quick response. I have already started calculating with 1 in the data sampling of her simulation start so was OK. Best regards, |
