Defining a fluid exchange activation interaction

A fluid exchange activation interaction allows you to activate a fluid exchange between two fluid cavities or between a fluid cavity and the environment.

Before you begin: You must create a fluid cavity and fluid exchange interactions.

  1. From the main menu bar, select Interaction Create .

    Tip: You can also create a fluid exchange activation interaction using the tool in the Interaction module toolbox.

  2. In the Create Interaction dialog box that appears, do the following:
    1. Name the interaction.

      For more information about naming objects, see Using basic dialog box components.

    2. Select the step.

      Fluid exchange activation is active only in dynamic steps.

    3. Select the Fluid exchange activation type of interaction.
  3. Click Continue to close the Create Interaction dialog box.

    Abaqus/CAE opens the Edit Interaction dialog box.

  4. Select an Amplitude to define a multiplier for the fluid exchange magnitude.

    Tip: Alternatively, you can click to create a new amplitude. For more information, see The Amplitude toolset.

  5. Enter the Delta leakage area to define the rate of the fluid leakage.
  6. Enter a list of Fluid exchanges that need to be activated in this step.
  7. Select Consider blockages by contacted surface to consider vent or leakage area obstruction by contacted surfaces.
  8. Select Allow outflow only if the flow is allowed only from the first fluid cavity to the second fluid cavity in the fluid exchange.
  9. Click OK to create the interaction and to close the editor.

    Symbols that represent the fluid exchange activation interaction that you just created appear in the viewport. For more information, see Understanding symbols that represent interactions, constraints, and connectors.
