Abstract: This paper presents some theoretical and numerical problems that arise in the analysis of coupled electromagnetic-thermal problems, and inverse problems in electromagnetic devices.
The main objectives of the paper are:
1. To present advanced techniques to assist in the development of algorithms and software products for analysis of coupled electromagnetic and thermal fields with emphasis on magneto-thermal and electro-thermal fields. We present the use of a number of techniques, which attempt to generate high-performance versions of existing sequential algorithms.
2. Some models of computation and their associated programming
3. To present algorithmic templates to areas of numerical computation of large-scale systems with emphasis on coupled elliptic and parabolic systems. These sets of templates will prevent future research workers having to re-invent the algorithmic basis to their applications. Such models of computation and their associated programming techniques may be used in solving a wide range of scientific problems. The templates may be used as building blocks in many other computational areas.
4. To present the domain decomposition in the context of the coupled fields and the finite element method. Parallel implementations of the algorithms are presented.
5. To present a unitary theory for inverse problems in the electrical engineering and to develop computational models for a variety of engineering applications.
6. To apply our techniques and templates to a number of engineering problems and report on the performance of our techniques.
