We present the results of first realistic simulations using our state-of- the-art MHD code on unstructured tetrahedral meshes in 3d. The code incorporates local grid adaption with dynamic load balancing and relies on a recently proposed approximate Riemann solver. We demonstrate that it is absolutely crucial to control the divergence of the magnetic field and that our new hyperbolic divergence cleaning approach works well also in 3d.
