Buildings.HeatTransfer.Data.Soil

Package with solid material for soil, characterized by thermal conductance, density and specific heat capacity

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).
