.IBPSA.Fluid.Sources.FixedBoundary

Information

This model defines constant values for boundary conditions:

• Boundary pressure or boundary density.
• Boundary temperature or boundary specific enthalpy.
• Boundary composition (only for multi-substance or trace-substance flow).

Note, that boundary temperature, density, specific enthalpy, mass fractions and trace substances have only an effect if the mass flow is from the Boundary into the port. If mass is flowing from the port into the boundary, the boundary definitions, with exception of boundary pressure, do not have an effect.

Revisions

• April 18, 2017, by Filip Jorissen:
  Changed checkBoundary implementation such that it is run as an initial equation since it depends on parameters only. See #728.
• January 26, 2016, by Michael Wetter:
  Added unit and quantity attributes.
• September 29, 2009, by Michael Wetter:
  First implementation. Implementation is based on Modelica.Fluid.
