Buildings.Fluid.Sources.Validation.BaseClasses.BoundarySystem

System model for testing of boundary condition

Buildings.Fluid.Sources.Validation.BaseClasses.BoundarySystem

Information

System model used to test the boundary conditions for different media. This model has been introduced to get access to the medium mass fraction, which is a protected variable in Buildings.Fluid.Sources.Boundary_pT. Therefore, this model has been created so that the boundary model has a port which is used to access the mass fraction.

Extends from Modelica.Blocks.Icons.Block (Basic graphical layout of input/output block).
