This paper is concerned with the application of the boundary element method with the analog equation method (AEM), proposed by Katsikadekis and Nerantzaki, and Green's theorem to analyze steady-state heat conduction in anisotropic solids. In this study, the linear differential operator (the Laplacian) of steady-state heat conduction in isotropic solids is extracted from the governing differential equation. The integral equation formulation employs the fundamental solution of the Laplace equation for isotropic solids, and therefore, from the anisotropic part of the governing differential equation, a domain integral arises in the boundary integral equation. This domain integral is transfprmed into boundary integrals using Green's theorem with a polynomial function. Mathematical formulations of this approach for two-dimensional problems are presented in detail. The proposed solution is applied to two typical examples, and the validity and other numerical properties of the proposed BEM are demonstrated in the discussion of the results obtained.
