Abstract
The eddy-current losses in a superconductive dipole magnet comprising a metallic beam tube are calculated. A standard 3-D Finite Element (FE) formulation is accomplished by a shell element representation of the thin beam tube. Thanks to the resulting reduced model size and the improved aspect ratio of the tetrahedra used for discretization, the computational time, in particular for transient nonlinear simulations, is reduced significantly.
