modelReservoir
Simple open tank model
Extends from Internal.PartialVolume.
Information
This is a volume, that is open at the top and therefore maintains environmental pressure at the top and adds pressure depending on fill height.
Conceptually it is a Sink and a Source. It therefore defines the level of inertial pressure r and acts as a loop breaker in a closed loop.
This component uses a simplification (medium.p is set to p_env + height*g, which is only correct at the bottom of the reservoir) which is intended to hold for media with low compressibility.
Note that the energy equation requires the mass in the system to be positive and will not give valid results otherwise (if the assert of height > 0 fails).
