LS-DYNA®R7:Update On The Electromagnetism Module (EM)

An electromagnetism module is being developed in LS-DYNA version R7 double precision for coupled mechanical/thermal/electromagnetic simulations. The physics, numerical methods and capabilities of this module will be introduced. Some examples of industrial applications will be presented. These include magnetic metal forming, bending and welding in different configurations, high pressure generation for equation of state studies and material characterization, induction heating, resistive heating, short circuits due to crashes, electromagnetic launchers, ring expansions, magnetic levitation and so forth. Additionally, magnetic material capabilities are currently available for beta testing and will also be discussed in this paper.
