An Automatic Mesh Generator Based CFD System to be used as a Design Tool

Abstract

A computational fluid dynamics (CFD) system is presented. The system, called SCRYU/Tetra, is based on an automatic tetrahedral mesh generator and has been developed as a design tool for engineers who are not necessarily fluid dynamics specialists, but are seeking better designs of their equipment through CFD analysis. In order to make the system useful for nonspecialists, efforts are taken so that the system can handle complicated geometry from CAD systems, does not require any special skill which is not essential for the understanding of the flow phenomenon itself, and is accurate enough to correctly identify the best design candidate from others. Microsoft WINDOWS PC’s are chosen as the main hardware platform to make the analysis cost low. The system has demonstrated an ability to complete analysis in a very short time (typically a few days) with satisfactory accuracy.
