GENSMAC: a computational marker and cell method for free surface flows in general domains
A computer program for solving two-dimensional incompressible viscous fluid flow in general domains is described. This is based on the simplified marker and cell technique, but it has a number of novel features. A user-supplied data file of coordinates prescribes the fluid domain which can be quite general and needs only to be connected. With a view to parallelisation the momentum equations are solved explicitly, but an automatic step-changing routine optimises the stability restriction. A conjugate gradient solver is used to invert the discrete Poisson equation. An accurate approximation to the stress conditions on the free surface is adopted.
