  1. Please describe your case

    I want to simulate internal flow in vacuum cleaner.

  2. Please describe velocity and pressure conditions

    face1 is inlet and face 2 & face 3 is outlet. face1 total pressure is 0 and face2&3 static pressure is -20pa. inlet velocity is induced by this pressure difference.

  3. Press the [Pressure, Velocity File Generate button] and wait until the p,U file is created.

    1. Sometimes not responding appears. It is waiting for the results from chatGPT, so please wait for a few minutes.
    2. When creation is complete, a pop-up will appear indicating that creation has been completed. Check whether the p,U file was created properly in the project folder/0 location.
