The density, conductivity, enthalpy and electrical conductivity should be defined for each material used in the simulation. These properties can either be constant or functions of the temperature. In the latter case, the number of temperature points should be defined, as well as the associated distribution.
The materials and their properties should all be defined in this section using:
Table 7.1: Defining Materials and Properties
| Add a new material. | |
| Change the name of a given material. | |
| Create a new material with the properties of the previous one. | |
| Remove a material from the list. |
Note: The enthalpy is referenced at 0 °C.
Phase changes are introduced using temperature distributions. If the material is ice, which melts just above the freezing point, the density, conductivity and enthalpy of water and ice should be given as functions of temperature across both the solid and liquid states with substantial density, conductivity and enthalpy jumps in a narrow range across the freezing point.
