Time step control is an important issue in free surface tracking since the surface-tracking algorithm is considerably more sensitive to the Courant number than in standard fluid flow calculations. Ideally, we should not exceed an upper limit in the region of the interface. In some cases, where the propagation velocity is easy to predict, the user …
