Short summary
A detailed description of the All Scale Atmospheric Model (ASAM) is presented. To include obstacles or orographical structures within the Cartesian grid, the cut cell method is used. Discretization is realized by a mixture of finite differences and finite volumes together with a linear-implicit Rosenbrock time integration scheme. Results of idealized test cases are shown, which include conservation tests as well as convergence studies with respect to model accuracy.
