This paper deals with the electrokinetic modeling of earthing systems by means of a sub-domain perturbation finite element technique. An axisymmetric problem is solved for each single grounding rod or cable. Its solution must then be corrected by taking into account the influence of the other rods and cables. The electric scalar potential is transferred from one problem to the other through projections between meshes. An inherently 3D problem can thus be solved as a succession of 2D sub-problems, which significantly speeds up the solution and enables to tackle complicated grounding systems. [less ▲]

Thin conductive magnetic shells are accounted for by means of two different time-domain magnetodynamic finite-element formulations, namely the magnetic field formulation and the magnetic vector potential formulation. Both approaches are an extension of the classical linear frequency-domain thin-shell approximation. The interface conditions for the magnetic field formulation and the vector potential formulation are expressed in terms of the average current density and the average flux density, respectively, together with a number of higher-order components of these quantities. The proposed time-domain thin-shell approaches are validated by means of a 3D magnetodynamic problem. The results are shown to agree well with those obtained with a fine model, whereas the computation time is significantly reduced. [less ▲]

In this paper, the authors propose a novel time-domain extension of the well-known frequency-domain thin-shell approach. The time-domain interface conditions at the shell surface are expressed in terms of the average (zero-order) instantaneous flux and current density vectors in the shell, as well as in terms of a limited number of higher-order components. The method is elaborated for a magnetic vector potential finite-element formulation. The validation is done by means of two 2-D test cases with pulsed magnetic field excitation. The results are in excellent agreement with those produced by a brute-force model in which the shell is meshed finely throughout its thickness. [less ▲]

The authors propose a novel nonlinear time-domain extension of the well-known frequency-domain surface-impedance method in computational magnetodynamics. Herein the 1-D eddy-current problem in a massive conducting region (semi-infinite slab) is considered via a number of exponentially decreasing trigonometric basis functions that cover the relevant frequency range of the application at hand. The resulting nonlinear equations are solved using the Newton-Raphson method. The method is validated by means of a simple 2-D test case. [less ▲]

We present a numerical method for the computation of wave scattering by convex three-dimensional obstacles, which exhibits a bounded computational complexity for arbitrarily high frequencies. The method is based on a combination of a high-frequency ansatz for the unknown density in a boundary integral formulation of the problem, and an extension of the ideas of the method of stationary phase to allow for the efficient integration of oscillatory functions. The method builds upon the ideas proposed in [2] and [1]. [less ▲]
