TGrid 5.0 Advances Automatic, High-Quality Meshing Tools

By DE Editors

ANSYS, Inc. (Southpointe, PA), a global innovator of simulation software and technologies designed to optimize product development processes, released version 5.0 of its TGrid advanced mesh generation software, which introduces new tools and enhanced capabilities to generate high-quality meshes more efficiently.

TGrid technology, a specialized preprocessor for fluid flow analysis, is used to create large unstructured tetrahedral and hex-core meshes for complex geometry. The software is used heavily in large-scale automotive and aerospace applications, in which advanced meshing techniques are required for the computational analysis of fluid flow.

TGrid 5.0 software addresses one of the most challenging meshing applications in today’s automotive industry, front-end underhood thermal management (UTM), says the release, by capturing best practices and automating the meshing required for this class of problems (at one time, this was a manual, time-consuming task). The surface wrapper method is newly equipped with a fully automatic leak/hole detection and fixing algorithm; this eliminates tedious manual cleanup of the often-dirty underhood geometry.

Plus, a single surface recovery technique for thermal shields is available in TGrid 5.0. Combined with shell conduction models available in FLUENT software, the result is efficient and accurate UTM solutions. The entire underhood wrapper-based meshing process has been encapsulated using journal file capabilities in TGrid for overnight batch execution.

With this release, a new tetrahedral meshing algorithm,  combining the speed of Delaunay and the quality of an advancing front, has been added to the TGrid meshing arsenal.
