Supergranulation scale (50 Mm wide by 20 Mm deep) simulations of solar convection are being relaxed thermally and dynamically. The initial state was made by duplicating a periodic smaller simulation of 24 Mm wide by 9 Mm deep and extending it in depth assuming constant entropy upflows and extrapolating the downflows. Relaxation is rapid near the surface, but very slow at large depths and large horizontal scales. Initial results are reported. These simulations will help separate the role of the second helium ionization zone from the effect of the increasing scale height with depth. This large size is also necessary for analyzing local helioseismic inversion techniques. Coriolis forces becomes significant on these spatio-temporal scales and we have added f-plane rotation to investigate the nature of the surface shear layer. Eventually, magnetic fields will be added to study the development and maintenance of the magnetic network.
