A Regular Indirect Boundary Element Method for Thermal Analysis

A Regular Indirect Boundary Element formulation is developed following a weighted residual approach. In this formulation, the fictitious source density, which appears in the integral equations of the method, is distributed on a surface which is exteriorly separated from the physical field boundary of the problem. This approach does not require the evaluation of singular integrals and produces u...

A Regular Boundary Element Method for Fluid Flow

The Boundary Element Method is now well established as a valid numerical technique for the solution of field problems, equal to the Finite Element Method in generality and surpassing it in computational efficiency in some cases.’ In this paper is presented a ‘Regular Boundary Element Method’ as applied to inviscid laminar fluid flow problems. It involves the formation of a system of regular int...

A Boundary Element Method for Substrate Cross-talk Analysis

An increasingly urgent topic for the realization of densely packed (mixed signal) integrated circuits is prevention of cross-talk via the substrate. Due to decreasing distances between components and increasing operating frequencies, the coupling between components and/or circuit blocks becomes stronger and affects the circuit behaviour more and more. This paper proposes a Boundary Element Meth...

GPU-accelerated indirect boundary element method for voxel model analyses with fast multipole method

An indirect boundary element method (BEM) that uses the fast multipole method (FMM) was accelerated using graphics processing units (GPUs) to reduce the time required to calculate a three-dimensional electrostatic field. The BEM is designed to handle cubic voxel models and is specialized to consider square voxel walls as boundary surface elements. The FMM handles the interactions among the surf...
