In this paper, an ( α , β , γ ) distance transformation is introduced for direct computation of 3D domain integrals, which is essential when employing the time-dependent boundary element method for the transient heat conduction problems. The gradual reduction of the time step to zero in the time-dependent integral kernel may result in near-singularity. In this situation, the direct application of Gaussian quadrature is ineffective for accurately calculating the domain integrals. To address this issue, a novel distance transformation incorpor...
