Abstract
The electromagnetic launcher at speed is a challenging computational proble m as fast time transient electromagnetic fields are involved and the veloci ty of the moving parts is designed to be very high. A large number of formu lations are now available for modeling the electromagnetic behavior of movi ng conductor devices in 3D, These methods vary in computational expense and accuracy. In this paper we describe and compare some of these methods, and show some examples.
