Information

Modelica.Media.Interfaces.Types.FluidLimits

Validity limits for fluid model

Information

The minimum pressure mostly applies to the liquid state only. The minimum density is also arbitrary, but is reasonable for technical applications to limit iterations in non-linear systems. The limits in enthalpy and entropy are used as safeguards in inverse iterations.
