The transient heat conduction problem in an anisotropic solid is difficult to solve analytically, and it seems most convenient to obtain the solution by numerical methods such as the finite difference method. In this paper, the following have been made clear. (1) Considering the accuracy of the solution and the stability of the finite difference equations, it is shown to be desirable to convert the anisotropic field into an isotropic one by enlarging the field along the principal axis, and then to apply the finite difference method. (2) The equation for modifying heat flux at the boundary, accompanied with the above conversion, is proposed, and the method to obtain the solution, which was reported in the former papers, is shown to be applicable to the anisotropic field. (3) The actual transient temperature change in two-dimensional multicrystalline carbon, which is regarded as orthotropic solid, agrees well with the finite difference solution by the method prescribed in this paper.
