Abstract: An integrated, microcomputer-based system has been developed for simulation of two-dimensional, unsteady, free surface flows. The system consists of a finite-element mesh generation code, a 2-D hydrodynamic code, and graphical post-processors. The mesh generation code was specifically designed for interactive construction of irregular meshes and automatic generation of input files to the hydrodynamic code. The hydrodynamic code was adapted from RMA-2 in the TABS-2 system of models. Graphical displays of water surfaces and velocities are presented. The microcomputer-based system provides engineers with a tool that can be applied to various studies of rivers, lakes, and estuaries. System usage and benchmarks for Macintosh and MS-DOS machines is provided. It provides economical and user-friendly desktop applications for most free surface flow problems.
