Moving Inlet/Outlet

The Moving Inlet/Outlet statistics provide time-resolved quantities describing the state, motion, and flow behavior of each moving inlet or outlet in the simulation. These outputs characterize how the inlet or outlet interacts with the surrounding fluid, including its position, orientation, flow rate, and local thermofluid properties. This output produces a tab-separated ASCII .txt file named MovingInletOutlet_{DynamicName}.txt, where the dynamic name corresponds to the name of the Moving Inlet/Outlet in the Model Tree.

The data is written as a time series, where each row corresponds to a simulation time, and each column corresponds to a statistic listed in the table below. Each row in the output file corresponds to a new statistics output time and is appended at the Statistics Output Write Interval.

The reported quantities fall into several categories:

  • Kinematics: Position, translation, and orientation vectors describe how the outlet moves and is oriented within the domain.

  • Flow Quantities: Flow rate and velocity components describe the magnitude and direction of fluid passing through the outlet.

  • Thermofluid Properties: Pressure, density, temperature, and scalar field values represent spatial averages at the outlet and provide insight into local flow conditions.

  • Geometry and State: Diameter defines the outlet size, while the open/close indicator specifies whether the outlet is actively passing flow.
