摘要
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. The code is written in structured FORTRAN with features from FORTRAN 90. The efficacy of the code is illustrated by applying it to some industrial problems. © 1994 by Academic Press, Inc.
