About Fluid Exchange Activation

When you activate fluid exchange definitions in a step, the simulation includes the effects of fluids flowing between fluid cavities or from a fluid cavity to the environment.

Activating Fluid Exchange for a Simulation

Fluid cavities and fluid exchange behaviors are specified as part of the model, but the simulation does not consider their effects unless you activate the fluid exchange in a simulation step. During fluid exchange activation, you can also specify the following: blockage behaviors, whether the fluid flows in one direction or both ways, and the relative size of the fluid leakage area.

  • Blockage behaviors
  • Whether the fluid flows in one direction or both ways
  • Relative size of the fluid leakage area

If your model has multiple fluid exchange behaviors, you can activate as many of them as you like in a single fluid exchange activation.
