چکیده
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 engineers. This paper outlines the basis of three-dimensional BEM design and analysis of magnetic devices, and contrasts 2D/3D design for optimal utilization of 3D. Options to test solution accuracy are discussed. The torque converter sample problem demonstrates the interactive graphics capabilities, the efficiency and power of BEM in the analysis of magnetic fields.

In this study, a set of self-consistent coupled-integral equations for the local magnetic flux and current distributions in a finite superconducting hollow cylinder under an axial magnetic field has been directly derived by using the Biot-Savart law within the framework of the critical-state model. The equations were first solved numerically in the three-dimensional space before obtaining the h...

In this study, stress and displacement functions of the three-dimensional theory of elasticity for homogeneous isotropic bodies are derived from first principles from the differential equations of equilibrium, the generalized stress – strain laws and the geometric relations of strain and displacement. It is found that the stress and displacement functions must be biharmonic functions. The deriv...
