Abstract : This paper documents the development and verification of two finite difference models that solve the general twodimensional form of the heat conduction equation, using the alternativedirection implicit method. Both can handle convective, constant flux, specified temperature and semiinfinite boundaries. The conducting medium may be composed of many materials. The first program, ADI, solves for the case where no change of state occurs. ADIPC solves for case where a freeze/thaw change of phase may occur, using the apparent heat capacity method. Both models are verified by comparison to analytical results. (Author)
