 In order to speed-up performance, the Poisson equation for perturbation pressure (see [[psolver]]) can be called only at the last substep of multistep Runge-Kutta timestep schemes (see [[timestep_scheme]]) by setting '''call_psolver_at_all_substeps''' = ''.F.''. In many cases, this sufficiently reduces the divergence of the velocity field. Nevertheless, small-scale ripples (2-delta-x) may occur. In this case and in case of non-cyclic lateral boundary conditions, '''call_psolver_at_all_timesteps''' = ''.T.'' should be used.

+In the model, the maximum allowed time step according to CFL and diffusion-criterion [[dt_max]] is reduced by dt = dt_max * '''cfl_factor''' in order to avoid stability problems which may arise in the vicinity of the maximum allowed timestep. The condition 0.0 < '''cfl_factor''' < 1.0 applies.\\\\
