A projection penalization approach for the high-order DG-FEM in the time domain

Radio Science, 2011

We investigate the Discontinuous Galerkin-Finite Element Method (DG-FEM) for the solution of Maxwell's equations in the time domain. The charge conservation laws are known to be violated by this method which consequently gives rise to spurious numerical solutions. It is, however, possible to introduce additional constrains in the formulation which impose charge conservation either exactly or approximately. In this work, ...

  • A projection penalization approach for the high-order DG-FEM in the time domain

    We investigate the Discontinuous Galerkin-Finite Element Method (DG-FEM) for the solution of Maxwell's equations in the time domain. The charge conservation laws are known to be violated by this method which consequently gives rise to spurious numerical solutions. It is, however, possible to introduce additional constrains in the formulation which impose charge conservation either exactly or approximately. In this work, a new approach based on a topological orthogonal projector into a high-order H(curl)-conforming approximation space is proposed. Using this approach we derive a constrained DG-FEM formulation which is strictly free of spurious modes. Furthermore, we construct a time domain penalization scheme which allows to separate the spurious modes related to unphysical charges from the physical solutions while maintaining accuracy and energy conservation.

  • Nonplanar trapezoidal tooth log-periodic antennas: Design and electromagnetic modeling

    Nonplanar trapezoidal tooth log-periodic (LP) antennas are investigated by combining the wisdom of theoretical design procedures with the power of accurate numerical simulation environments. Once the theoretical design is completed, electromagnetic simulations employing accurate integral equation solvers are utilized to test and correct the original design. A two-element array of trapezoidal tooth LP antennas is designed. The array features beam- steering ability as a novelty, in addition to frequency independence and higher directivity. Beam steering is achieved by optimizing the excitation coefficients of the two LP antennas.

  • Contraction integral equation method in three-dimensional electromagnetic modeling

    The integral equation method has been proven to be an efficient tool to model three-dimensional electromagnetic problems. Owing to the full linear system to be solved, the method has been considered effective only in the case of models consisting of a strongly limited number of cells. However, recent advances in matrix storage and multiplication issues facilitate the modeling of horizontally large structures. Iterative methods are the most feasible techniques for obtaining accurate solutions for such problems. In this paper we demonstrate that the convergence of iterative methods can be improved significantly, if the original integral equation is replaced by an equation based on the modified Green's operator with the norm less or equal to one. That is why we call this technique the Contraction Integral Equation (CIE) method. We demonstrate that application of the modified Green's operator can be treated as a preconditioning of the original problem. We have performed a comparative study of the convergence of different iterative solvers applied to the original and contraction integral equations. The results show that the most effective solvers are the BIGGSTAB, QMRCGSTAB, and CGMRES algorithms, equipped with preconditioning based on the CIE method.

  • INTRODUCTION TO ELECTRICAL ENGINEERING SIMULATION

    Theoretical modeling‐based analysis is a process where a model is set up based on laws of nature and logic, using mostly mathematics, physics, and engineering‐ initially with simplified assumptions about their processes and aiming at finding an input/output model. Integrators and function generation can accomplish simulation of an ordinary differential equation (ODE). A state‐space formulation allows mathematical implementation with ODE solvers that can be computed by MATLAB and supports the definition of a block diagram for signal modeling simulators, such as Simulink. State variables are directly related to the energy storage elements of a system, and the ODEs can be derived from nodal or mesh analysis. ECAP was the first general program for solving time‐varying circuit equations. Differential equation‐based systems are developed and simulated from practical examples that focus typical electrical circuit applications, energy conversion, renewable energy sources, interconnection of distributed generation, power electronics, power systems, and power quality problems.

  • Simulation of emergency evacuation in virtual reality

    A virtual reality system was developed to simulate emergency evacuations during fires. The spreading of the flame and smoke in the virtual fire was modeled based on numerical fire simulations, so that the conditions are similar to real life. A multi-grid, multi-base-state database model was used to overcome the disadvantages of traditional smoke spreading simulations. Textured images and particle systems provide visualization of the flame and smoke. The system immerses the user in a virtual environment with detailed interactions between the users and the virtual environment. The system can show which evacuation methods are effective for building safety evaluations.

  • A framework for next-generation radiation belt models

    The trapped radiation specifications, such as AE-8 and AP-8, are based upon a simple and reasonable framework that happens to be insufficient to the modern demands placed upon them. This manuscript outlines an improved framework for the next generation of radiation models. While existing radiation specifications tend to provide mean fluxes on a grid in magnetic coordinates, scientific and engineering users are starting to demand capabilities that are far beyond this simple framework, such as error bars on total mission dose and real-time data assimilation. One framework that can provide these added capabilities while still remaining fairly simple is the joint probability distribution, described here. The joint distribution can describe the behavior of individual fluxes on a grid in magnetic coordinates while also describing how those fluxes vary together. This covariance is a crucial ingredient for data assimilation and for proper error bars and percentiles on composite quantities like dose or fluence to a shielded device. This manuscript describes the core math of the proposed framework, an approach to building the model from in situ observations and/or numerical simulations, how to use the model to calculate error bars and percentiles on composite quantities, how to use the model in data assimilation, and how to make a first estimate of the dependence of worst case fluences on aggregation time.

  • Fuzzy programming models for vendor selection problem in a supply chain

    This paper characterizes quality, budget, and demand as fuzzy variables in a fuzzy vendor selection expected value model and a fuzzy vendor selection chance-constrained programming model, to maximize the total quality level. The two models have distinct advantages over existing methods for selecting vendors in fuzzy environments. A genetic algorithm based on fuzzy simulations is designed to solve these two models. Numerical examples show the effectiveness of the algorithm.
