Abstract

If the initial temperature is assumed to be constant, the boundary ele- ment method (BEM) does not need a domain integral in unsteady heat con- duction problems without heat generation. However, under heat generation or nonuniform initial temperature distribution, the domain integral is necessary. This paper shows that the two-dimensional problems of un- steady heat conduction with heat generation and initial temperature can approximately be solved without the domain integral by the improved multiple-reciprocity boundary element method. In this method, the domain integral in the each step is divided into point, line and area integrals. 1 Introduc
