Modeling of magnetic devices with finite-element methods
This report discusses the application of finite-element methods to the solution of magnetostatic field problems. A brief description is given of the finite-element representation of the magnetostatic field. Two computer codes which solve this problem are described. The code MAGNUM is commercially available and the code ISO is a Sandia in-house product. Both codes are currently available on the Sandia CRAY. Some general remarks are presented on modeling techniques and boundary conditions. A new method for estimating solenoid magnetic forces and dynamic response is described. A suite of codes for generating various electromagnetic devices is briefly discussed. Finally, some numerical results are presented. 6 refs., 10 figs.
