.Modelica.Fluid.Types.PortFlowDirection .Modelica.Fluid.Types.PortFlowDirectionEnumeration to define the assumptions on the model for the direction of fluid flow at a port (to be selected via choices menu):
| PortFlowDirection. | Meaning |
|---|---|
| Entering | Fluid flow is only entering the port from the outside |
| Leaving | Fluid flow is only leaving the port to the outside |
| Bidirectional | No restrictions on fluid flow (flow reversal possible) |
The default is "PortFlowDirection.Bidirectional". If you are completely sure that the flow is only in one direction, then the other settings may make the simulation of your model faster.
type PortFlowDirection = enumeration(Entering "Fluid flow is only entering", Leaving "Fluid flow is only leaving", Bidirectional "No restrictions on fluid flow (flow reversal possible)");
