“…Some techniques for modeling devices with little information about their hardware have been developed lately. In [2], some models for automotive devices based on Very High Speed Integrated Circuits Hardware Description Language (VHDL) have been proposed. In this work, simple impedances have been used for modeling the electrically short components.…”

This paper explores how much detailed an automotive electric system geometry can be to optimize simulation computational effort. For this purpose, simulations related to two kinds of analysis -crosstalk and external radiated disturbancehave been run through a Finite Element Method (FEM) based software and a Circuit Theory based one. Crosstalk simulated signals in time domain have been statistically compared with an inside vehicle measurement. Different complexity models have been tested in this correlation process. This procedure has been used to verify automotive geometric models' accuracy for a certain frequency range. The main goal is to verify the computational savings by using some techniques and suppressing some negligible details of car's geometry.

“…Moreover, PEECmethod has been employed to study EMC in various type of problems, including automotive industry [3], power electronics [4] and filter layout optimization [5]. Additionally, extending the PEEC-method to be able to handle non-orthogonal structures by taking advantage of parallel computer systems will provide the possibility to perform EMC analysis on real world problems with complex structures.…”

Abstract-A parallel implementation of a quasi-static Partial Element Equivalent Circuit (PEEC)-based solver that can handle electromagnetic problems with non-orthogonal structures is presented in this paper. The solver has been written in C++ and employs GMM++ and ScaLAPACK computational libraries to make the solver fast, efficient, and adaptable to current parallel computer systems. The parallel PEEC-based solver has been tested and studied on high performance computing clusters and the correctness of the solver has been verified by doing comparisons between results from orthogonal routines and also another type of electromagnetic solver, namely FEKO. Two non-orthogonal numerical test cases have been analysed in the time and frequency domain. The results are given for solution time and memory consumption while bottlenecks are pointed out and discussed. The benchmarks show a good speedup which gets improved as the problem size is increased. With the capability of the presented solver, the non-orthogonal PEEC formulation is a viable tool for modelling geometrically complex problems.
