Directional dependence of thermal conductivity
Isotropic, orthotropic, or fully anisotropic thermal conductivity can be defined. Only isotropic thermal conductivity can be defined for an incompressible fluid dynamic analysis that includes an energy equation. For orthotropic or anisotropic thermal conductivity, a local orientation (Orientations) must be used to specify the material directions used to define the conductivity.
Isotropic conductivity
For isotropic conductivity only one value of conductivity is needed at each temperature and field variable value. Isotropic conductivity is the default.
