“…The idea of using FEM-BEM methods for solving eddy current problems in dimension three has been exploited in several works of Bossavit [5,6,8,9]. The main idea of such an approach consists in providing non-local boundary conditions for a finite element treatment of the problem in the conductor Ω where the eddy currents are to be computed.…”

“…This method has been implemented in a code named TRIFOU (cf. [5]) but, at the authors knowledge, an analysis of this coupling scheme is not available. In any case, the analysis of the Johnson-Nédélec method requires an hypothesis that constitutes a severe limitation in practice: the interface boundary Γ := ∂Ω must be regular since the term associated to the double layer potential must be considered as a compact perturbation, cf.…”

“…As an ECT problem, we adopted the standard one proposed in the TEAM workshops for eddy current code comparison [4] and also presented in some papers [7,8]. The test piece is a rectangular block 330x285x30mm with a 40x0.5x10mm flaw on the center of one of the larger faces, as shown in Fig.!.…”

“…Fu11"3-D programs have been rea1ized [4,5], but are not used for ferromagnetic materia1s and are very expensive in CPU time (they are imp1emented on vectoria1 computers, Cray 1 or Cyber 205). The aim of our study is to rea1ize a 3-D program for sma11 skin depth prob1ems which can be performed on a mini-computer (HP 9000, VAX 780) with a "reasonab1e" CPU time.…”
