modelVesselLevel
Extends from VesselPhysical.
Information
Adds the relationship between liquid filled level and volume to the VesselPhysical model.For now the relationship between liquid level and liquid volume is coded only for spheric and vertical cylindrical vessels.
For vertical vessels the relationship covers only the bottom and the cylindrical shell.
