Advanced numerical simulation of pulsed magnets with a finite element method

The performance of a 70 T pulsed magnet with internal and external reinforcement is simulated with an advanced finite element method. The discharge analysis, thermal analysis and stress analysis are calculated with the 'coupled field analysis' scheme for the ANSYS model 'voltage-fed stranded coil'. The results show that the finite element technique is a useful tool for the design of pulsed magnets. These are compared to results obtained by simple one-dimensional codes, and the respective advantages of both methods are pointed out. Data from a recently tested high performance coil are given; test results are in good agreement with the calculations.
