AnisoHeatConductionMaterial

General-purpose material model for anisotropic heat conduction

Description

The material model AnisoHeatConductionMaterial is used to model a material with anisotropic thermal properties. The thermal conductivity is represented as a rank two tensor: (1)

It is mandatory for the user to supply the parameter thermal_conductivity as a vector with nine element ' '. The thermal conductivity can be set as a function of temperature () by providing the parameters thermal_conductivity_temperature_coefficient_function () and the reference_temperature (). The thermal conductivity as a function of temperature is expressed as:

where is the thermal conductivity based on the user supplied vector. The specific heat capacity can be supplied either as a constant value or as a function using the parameter specific_heat.

It should be noted that in some analyses the thermal conductivity could potentially depend on other variables (e.g. solute concentration). The user should provide off diagonal Jacobian contributions in these analyses.
