A material's thermal conductivity:
must be defined for “Uncoupled heat transfer analysis,” Section 6.5.2; “Fully coupled thermal-stress analysis,” Section 6.5.4; and “Coupled thermal-electrical analysis,” Section 6.6.2;
can be linear or nonlinear (by defining it as a function of temperature);
can be isotropic, orthotropic, or fully anisotropic; and
can be specified as a function of temperature and/or field variables.
Isotropic, orthotropic, or fully anisotropic thermal conductivity can be defined. For orthotropic or anisotropic thermal conductivity, a local orientation (“Orientations,” Section 2.2.5) must be used to specify the material directions used to define the conductivity.
For isotropic conductivity only one value of conductivity is needed at each temperature and field variable value. Isotropic conductivity is the default.
