Buildings.HeatTransfer.Data.Soil

Information

Package with records for solid materials. The material is characterized by its thermal conductivity, mass density and specific heat capacity.

These properties are used to compute heat conduction in circular coordinates. Hence, as opposed to Buildings.HeatTransfer.Data.Solids, they do not include the material thickness and the generation of the spatial grid.

Extends from Modelica.Icons.MaterialPropertiesPackage (Icon for package containing property classes).

Buildings.HeatTransfer.Data.Soil.Generic

Information

Generic record for solid materials used as soil. The material is characterized by its thermal conductivity, mass density and specific heat capacity.

Extends from Buildings.HeatTransfer.Data.BaseClasses.ThermalProperties (Thermal properties of materials with storage).

Parameters

Type	Name	Default	Description
ThermalConductivity	k		Thermal conductivity [W/(m.K)]
SpecificHeatCapacity	c		Specific heat capacity [J/(kg.K)]
Density	d		Mass density [kg/m3]
Boolean	steadyState	(c == 0 or d == 0)	Flag, if true, then material is computed using steady-state heat conduction
