Test Case

Heat conduction in a solid with anisotropic thermal conductivity is modeled. Two opposite walls are maintained at uniform temperatures. Conductivity of the solid material is specified using matrix components to account for the anisotropy. The simulation results are compared with analytical solution for temperature distribution.
