| Abstract: | Boundary integral and its discrete equations are established usingweighed residue method for the isotropic and steady- state cases inthree-dimensional temperature field. Analytic expressions are derivedfor two singular integrations which occur in the steady- state tempe-rature field when using boundary element method. The domain ofintegration and the symmetrization of coefficient matrix are discussedin detail. Advantages as simple, rapid and reliable in computationare shown through examples included. |
