Buildings.Fluid.MixingVolumes.BaseClasses.Validation

Collection of validation models

Information

This package contains validation models for the classes in Buildings.Fluid.MixingVolumes.BaseClasses.

Note that most validation models contain simple input data which may not be realistic, but for which the correct output can be obtained through an analytic solution. The examples plot various outputs, which have been verified against these solutions. These model outputs are stored as reference data and used for continuous validation whenever models in the library change.

Extends from Modelica.Icons.ExamplesPackage (Icon for packages containing runnable examples).
