    Description / Table of Contents: Übersicht Die Optimierung der supraleitenden Diplomagnete für den `Large Hadron Collider' (LHC) zielt auf die Erzeugung eines extem homogenen Feldes ab. Durch Anwendung der BEM-FEM Kopplung wird das Feldproblem zerlegt, und zwar in die Berechung des Vektorpotentials allein aufgrund der Spule und des reduzierten Vektorpotentials aufgrund der Magnetisierung des Eisens. Dadurch können numerische Fehler bei der Berechnung des Spulenfeldes vermieden werden. Spule und umgebende Luftgebiete brauchen ausserdem nicht im Finite-Elemente Netz berücksichtigt zu werden. Dies vereinfacht die Modellbildung und vermeidet den Einfluss künstlich eingeführter Fernfeld-Randbedingungen.
    Notes: Contents The design and optimization of the superconducting dipole magnets for the Large Hadron Collider (LHC), is dominated by the requirement of an extremely uniform field. With the application of the BEM-FEM coupling method, the field problem is decomposed into the calculation of the source vector potential, and the reduced vector potential resulting from iron magnetization. The numerical errors do not influence the dominating contribution from the superconducting coil and the surrounding air region needs not to be meshed. This simplifies the preprocessing and avoids artificial boundary conditions at some “far” boundaries.
