Summary: If the initial temperature is assumed to be constant, the boundary element method does not need a domain integral in unsteady heat conduction 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 unsteady 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 each step is divided into point, line and area integrals.
