Abstract	Modeling of various shaped charge jet configurations has been undertaken using two commercially available numerical tools; AUTODYN and ELEKTRA. AUTODYN assumes the current is confined to the surface of the jet and uses finite volume techniques to simulate the applied electromagnetic pressure and the jet's subsequent deformation. ELEKTRA uses the finite element method to solve the low frequency subset of Maxwell's equations, in order to generate an accurate prediction of the current and magnetic flux density within the jet. The results from AUTODYN and ELEKTRA are compared in order to test the accuracy of the simplified approach used in AUTODYN and to evaluate the validity of the assumptions that have been made. These findings are then used to propose a way forward concerning the future coupling of AUTODYN and ELEKTRA.
