Description
We present a suite of simulations of a vertical stratified box with extents of +- 20 kpc and a footprint of 1 kpc^2 including self-gravity, supernova feedback, magnetic fields and a resolution of 2pc. We are able to resolve the ISM structure in the disk midplane and follow SN ejecta using tracer particles based on an Monte-Carlo advection scheme. The large vertical extents allow us to follow galactic fountains and investigate if galactic reaccretion of ejecta plays a role in uniformely mixing ejecta into the ISM. Additionally we are able to look at initial conditions for cloud formation, in particular spread in initial metallicities. Lastly we will have an estimate of how long it takes to form an equilibrated distribution (if there is one) of ejecta throughout the disk.
