This paper focuses on the acceleration of the hybrid finite element-boundary element analysis of 2D eddy current problems by means of the fast multipole method. An adaptive truncation scheme for the expansion of the 2D Laplace Green function is proposed. A linear time harmonic test case is considered. The results obtained with the hybrid model, with and without fast multipole acceleration, agree well with those obtained with a finite element model. The computational cost of the three calculations is compared and discussed. The proposed adaptive truncation scheme significantly contributes to the computation time savings achieved with the fast multipole method, particularly when dealing with moderate sized problems.

This paper deals with the acceleration of the hybrid finite-element/boundary-element analysis of three-dimensional (3-D) eddy-current problems by means of the fast multipole method. An adaptive truncation scheme for the multipole expansion of the 3-D Laplace Green function is proposed. As an application example, the TEAM workshop problem 28 is considered. The computational cost without and with fast multipole acceleration is discussed. [less ▲]

Pérennisant le thème abordé par les conférenciers dans la première partie de la journée, le discours du Recteur Willy LEGROS était quant à lui axé sur le "Dialogue des cultures? Civilisation universelle". Tout un chacun s'accorde sur le fait que l'homme fasse partie du monde, mais, derrière cette évidence, la vie des êtres humains se décline en une multitude de réalités qui se succèdent à tranvais le temps et dans l'espace. Elles se traduisent tant en théories qu'en pratiques diverses, plus souvent opposées que complémentaries. Le monde de l'un n'est pas le monde de l'autre. C'est une réalité de l'histoire et de la géographie. Et c'est bien là le problème. Cette source de diversité n'a jamais cessé d'être source de malentendus. Chaque groupe, chaque société, chaque interprétation du monde ont en effet rarement résisté à la facilité de se concevoir comme meilleurs, plus forts ou plus justes. Il en a régulièrement résulté des conflits, des tentatives de domination voire d'élimination des uns par les autres. [less ▲]

The present paper deals with the fast multipole acceleration of the 2D finite element-boundary element modelling of electromechanical devices. It is shown that the fast multipole method, usually applied to large 3D problems, can also lead to a reduction in computational time when dealing with relatively small 2D problems, provided that an adaptive truncation scheme for the expansion of the 2D Laplace Green function is used. As an application example, the 2D hybrid modelling of a linear actuator is studied, taking into account saturation, the voltage supply and the mechanical equation. The computational cost without and with fast multipole acceleration is discussed for both the Linear and nonlinear case. [less ▲]
