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.
