Numerical Von Karman dynamo  Y. Ponty*, S. Kreuzahler, N. Plihon, H. Homann and R. Grauer  Universite´ de la Coˆte d’Azur   We present a direct numerical simulation (DNS) of the Von Karman flow, forced by two  rotating  impellers.  The cylinder geometry and the  rotating  objects are modeled via a penalization method and implemented in a massive parallel pseudo- spectral solver. The MHD equations are solved in the vessel and inside the impellers. We will present several common features with the VKS dynamo experimental cam- paigns, as the observed magnetic mode (m=0) and the variation with the magnetic permeability. But we will discuss also about news features involving transition from the mode (m=1) to a new mode (m=0) even at low magnetic permeability.                10
