Models of components with ideal gases as working fluid

Extends from Modelica.Icons.Package (Icon for standard packages).

Information

This package contains models of physical processes and components using ideal gases as working fluid.

All models with dynamic equations provide initialisation support. Set the initOpt parameter to the appropriate value:

  • Choices.Init.Options.noInit: no initialisation
  • Choices.Init.Options.steadyState: full steady-state initialisation
  • Choices.Init.Options.steadyStateNoP: steady-state initialisation (except pressure)
  • Choices.Init.Options.steadyStateNoT: steady-state initialisation (except temperature)
The latter options can be useful when two or more components are connected directly so that they will have the same pressure or temperature, to avoid over-specified systems of initial equations.
