We investigate the launching process of jets from accretion disks by means ofaxisymmetric MHD simulations. Here, we present results of numerical MHD simulationsinvestigating how magnetic diffusivity and numerical resolution may affect theejection-to-accretion fraction and the asymptotic outflow structure.
