2. Level of detail, physical effects considered, and physical insight

(no remarks)

3. Limits of validity

(no remarks)

4. Interfaces

gasportIn: inlet for real gas

gasportOut: outet for real gas

5. Nomenclature

(no remarks)

6. Governing Equations

(no remarks)

7. Remarks for Usage

Use of this model can lead to warnings like "Differentiating (if pipe_xy.iCom.m_flow_in[1] > 0.0 then junction_beforePipe.gasBulk.xi[1] else junction_beforePipe.gasBulk.xi[1]) under the assumption that it is continuous at switching.". This can be ignored as long as the composition is set to the same value in every component (even in sinks etc.).

8. Validation

(no remarks)
