Abstract

A BEM method for transient heat conduction in heterogeneous media is presented, which builds upon the generalized boundary integral method developed by Kassab and Divo[l]. Using the Laplace transform, the time dependence is removed temporarily, and the governing equation is solved in the Laplace domain, hence eliminating the need to march the solution in time. Numerical results for variable conductivity are shown to be in excellent agreement with analytical solutions. 1 Introduction Problems involving isotropic or anisotropic heterogeneous media used to pose a serious challenge for the BEM, since the Green free space solutions on which it relies
