A Dual-Primal Finite Element Tearing and Interconnecting Method Combined with Tree-Cotree Splitting for 3-D Eddy Current Problems

Published by . Filed under . Total of no comments in the discussion.

Wang Yao with Advisors J.M. Jin and P.T. Krein The dual-primal finite element tearing and interconnecting (FETI-DP) method is adopted together with the tree-cotree splitting (TCS) method to shorten the computation time of 3-D eddy current problems. The FETI-DP method, among various domain decomposition methods, can provide a balanced load distribution over processors. Therefore, it […]

The Application of Time-Domain Finite Element Method to the Simulation of Three-Dimensional Benchmark Problems

Published by . Filed under . Total of no comments in the discussion.

Peng Chen with Advisors J.M. Jin and P.T. Krein Accurate nonlinear simulations of electric machines are increasingly important for optimizing system arrangements. The goal of this work is to apply the time-domain finite element method (TDFEM) to simulate the three-dimensional (3-D) nonlinear machine problem. The performance of the TDFEM method was first investigated using a […]

Accelerating Induction Machine Finite-Element Simulation with Parallel Processing

Published by . Filed under . Total of no comments in the discussion.

Christine Ross with Advisor P.T. Krein The research goal is to explore the acceleration potential of incorporating graphic-processing units (GPUs) for induction machine (IM) numerical field analysis. Characteristics of IM electromagnetic behavior essential to accurately simulate IMs have been studied. Using MATLAB’s Parallel Computing Toolbox, a two-dimensional finite element (FE) time-domain simulation of a benchmark […]

A Composite Material Approach Towards Induction Machine Design

Published by . Filed under . Total of no comments in the discussion.

Matthew Magill with advisor P.T. Krein This work examines the underlying structure of the modern induction machine, and its similarity to past arrangements created using design tables and empirical rules. To investigate limitations of the induction process, rather than a particular system arrangement, simplified planar layer induction machine models are considered within a compositestructure framework.
