Abstract
The conventional boundary element method (BEM) uses internal cells for the
domain integrals when solving nonlinear problems or problems with domain
effects. In the conventional BEM, however, the merit of the BEM, which is easy
preparation of data, is lost. This paper presents numerical integration for a
three-dimensional meshless BEM, which does not require the use of internal
cells. This method uses arbitrary internal points instead of internal cells. In this
paper, a three-dimensional interpolation method is proposed. Furthermore,
three-dimensional numerical integration is proposed using the above-mentioned
three-dimensional interpolation method. This method is based on an improved
multiple-reciprocity BEM (triple-reciprocity BEM) for heat conduction analysis
with heat generation. In order to investigate the efficiency of this method, several
numerical exa
