✦ Synopsis

A new method is presented for the simulation of two-dimensional, incompressible, free surface ¯uid ¯ow problems. The surface marker and micro cell (SMMC) method is capable of simulating transient free surface ¯uid ¯ow problems that include multivalued free surfaces, impact of free surfaces with solid obstacles and converging ¯uid fronts (including wave breaking). New approaches are presented for the advection of the free surface, the calculation of the tentative velocity, ®nal velocity and pressure ®elds and the use of multivalued velocities to treat converging ¯uid fronts. Simulation results are compared with experimental results for water sloshing in a tank to demonstrate the validity of the new method. Convergence of the new method is demonstrated by a grid re®nement study.
