PartialTwoPortPartial component with two ports |

Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This partial model defines an interface for components with two ports.
The treatment of the design flow direction and of flow reversal are predefined based on the parameter allowFlowReversal.
The component may transport fluid and may have internal storage for a given fluid Medium.
An extending model providing direct access to internal storage of mass or energy through port_a or port_b
should redefine the protected parameters port_a_exposesState and port_b_exposesState appropriately.
This will be visualized at the port icons, in order to improve the understanding of fluid model diagrams.
