Abstract :
Summary form only given. We investigate the three-dimensional dynamics of X- and Z-pinches using the NRL 3D Hall MHD code VooDoo. The goal is to determine the final magnetic field structure for different initial perturbations or non-equilibrium states in both the ideal MHD and the Hall MHD limit. The VooDoo code has successfully studied the nonlinear Hall dynamics of the current layer and magnetic reconnection in both 2D and 3D simulation studies. In the current study we conclude that there is tendency for establishing a force free helical magnetic field topology in many cases. Influence of resistivity on the process of force free configuration formation will be also analyzed by 3D hybrid code Dolphin used at UNR. We will compare our results with several experimental results
