All models use the `StandardWater` medium model by default, which is in turn set to `Modelica.Media.Water.StandardWater` at the library level. It is of course possible to redeclare the medium model to any model extending `Modelica.Media.Interfaces.PartialMedium` (or `PartialTwoPhaseMedium` for 2-phase models). This can be done by directly setting Medium in the parameter dialog, or through a local package definition, as shown e.g. in `Test.TestMixerSlowFast`. The latter solution allows to easily replace the medium model for an entire set of components.

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)
