However, you will notice if you run the simulation with a time-step size of 1e-6, you will obtain the same results as with a time-step size of 1e-5.
To recreate this graph, you can use the same Fluent cell as before, just make sure to re-initialize and to change the file name of the data export before re-running the simulation with a new time-step size. Then in CFD-Post you can simply load the new results in with the previous results. Remember that you can toggle which lines are visible under the "Line Display" tab of the chart you created.

The time-step size is highly dependent on the physics of the problem, so don't expect to be able to use the same time-step size for different physical problems. |
