Abstract

This paper presents a spectral element finite element scheme that efficiently solves elliptic problems on unstructured hexahedral meshes. The discrete equations are solved using a matrix-free preconditioned conjugate gradient algorithm. An additive Schwartz two-scale preconditioner is employed that allows h-independence convergence. An extensible multi-threading programming API is used as a common kernel language that allows runtime selection of different computing devices (GPU and CPU) and different threading interfaces (CUDA, OpenCL and OpenMP). Performance tests demonstrate that problems with over 50 million degrees of freedom can be solved in a few seconds on an off-the-shelf GPU., Comment: 23 pages, 7 figures

44. Optimization of the width of a thin plate in a transverse flux induction furnace

Abstract

This paper presents the analysis of a transverse flux induction furnace. The originality of the analysis presented in this paper is to use successively three different formulations in order to solve the magneto-thermal coupled problem. The Whitney elements (node based, edge based, facet based and volume based elements) are shown to be a convenient mean to perform naturally that coupling and to fullfil convergence conditions for the iterative solver. Index terms - Coupling, eddy currents, electromagnetic heating, finite element methods, induction heating, thermal devices.

45. Error estimation on a new principle of projection and reconstruction

Author

Subjects

Abstract

A new approach for error estimation in finite element computations is presented. This method may be applied to a wide range of modeling (magnetostatics, magnetodynamics, scattering problems). The main idea is to reconstruct, from the finite element solution of a primal formulation, a field belonging to the space of the dual finite element formulation. The error is then computed through the non fulfillment of the constitutive relation by the couple: primal solution-dual solution. 2-D problems with analytical solutions are treated to prove the efficiency of the method. Then the error estimator is used to adapt the mesh for a 3-D magnetostatic problem. Index terms - Error analysis, finite element method, adaptative meshing, modeling, magnetostatics, magnetodynamics.

50. On the resolution of magnetostatic and magnetodynamic mixed formulations

Author

Remacle, J.-F., Henrotte, F., Genon, A., Legros, W., and Dular, P.

Subjects
Magnetism -- Research, Maxwell equations -- Usage, Business, Electronics, Electronics and electrical industries
Abstract

Mixed formulations of Maxwell's equations are presented and the nature of the matrices appearing in these formulations is discussed. The point is made to their indefinite character. A method for solving these unusual matrices is then developed and applied to a test problem.
