The aim of this session is to provide a platform for any kind of research which is based primarily on numerical models rather than data analysis. This may include models of planetary interior, subsurface, surface or atmospheric processes. As most sessions about terrestrial planets concentrate on results from recent missions, this session is meant to present results from numerical models which might be based on mission results but do not have to be. Presentations about modeling of icy moons and other small bodies are also welcomed.
