A formulation and an implementation of two-dimensional Boundary Element Method (BEM) analysis for steady state, uncoupled thermoelastic problems is presented. This approach differs from other treatments of thermal loads in BEM analysis in which the domain integrals due to the thermal gradients are to be incorporated in the analysis via particular-integrals. Thus unlike Finite Elements or Field ...

A particle accelerated computational fluid dynamics (CFD) boundary element method (BEM) technique is proposed that allows the total sound pressure field produced by low Mach number flow past a rigid body to be predicted. An incompressible CFD solver is used to calculate the transient hydrodynamic flow field. The CFD/BEM coupling technique is then used to compute the acoustic pressure and pressu...

To predict the sound field in an acoustic problem, the well-known non-uniqueness problem has to be solved. In a departure from the common approaches used in the prior literature, the weak-form of the Helmholtz differential equation, in conjunction with vector test-functions, is utilized as the basis, in order to directly derive non-hyper-singular boundary integral equations for the velocity pot...

The forward problem in Electrical Impedance Tomography (EIT) requires an accurate estimation of its solution. Although analytical solutions exist for a limited number of cases, there is no suitable analytical solution for the geometry of the human head. A commonly adopted method is the use of Finite Element Methods (FEM). However, the human head consists of layers, which include the scalp and C...

Boundary element method (BEM) is a powerful computational tool for analysing piezoelectric problems. The BEM has been so well developed during the past 40 years that it has been considered as a very popular computational tool. This method consists of formulating the engineering problem in terms of an integral equations relating only boundary values and determining its solutions numerically. Thu...

In this paper, to investigate the effects of interference resulting from the standard setting of Block Edge Mask (BEM), assuming the use of LTE systems in the Digital Dividend, the minimum separation distances according to the size of guard band between DTV transmitter and LTE base station for a specific BEM are calculated.

This is a final report for the DIMACS grant of student-initiated project. I implemented Boundary Element Method(BEM) using Java. The system is tested with Rutgers Master II haptic glove. This report covers related background research, implementation of BEM and experiment results.

Increasingly complex electromagnetic devices require more flexible modelling, and fast and accurate computation of performance parameters. Although two-dimensional analysis provides good approximations, often the physics of the problem requires three-dimensional analysis. Using the Boundary Element Method (BEM) for three-dimensional analysis, now provides unprecedented design opportunities to e...

The use of air-conditioning systems is expected to increase as a consequence of global-scale and urban-scale climate warming. In order to represent future scenarios of urban climate and building energy consumption, the Town Energy Balance (TEB) scheme must be improved. This paper presents a new building energy model (BEM) that has been integrated in the TEB scheme. BEM-TEB makes it possible to ...

We describe a hybrid method which combines the boundary element method (BEM) and the finite element method (FEM) to compute circuit models for layout dependent capacitances. The method can handle irregularities in the stratification of the layout of the integrated circuits (IC’s). New in the method are the models for the interface between the regions where the BEM and the FEM are applied. We sh...
