MaterialLib::Fluid::FluidPropertiesWithDensityDependentModels Class Reference

Detailed Description

A class contains density, viscosity, heat_capacity and thermal_conductivity models, which are all functions of temperature, density and concentration.

Attention

The density must be computed firstly, i.e. first call getValue(PropertyType::density, variable_values).
