TGrid™ software is a specialized pre-processor for fluid flow analysis. It is used to create
large, unstructured tetrahedral and hexcore meshes for complex geometries. TGrid
software is utilized heavily for large-scale automotive and aerospace applications in which
advanced meshing techniques are required for the computational analysis of fluid flow.
Customers and Applications
Automotive industries around the world are pushing productivity on new car models,
resulting in the demand for rapid and high-quality solutions for large-scale computational
fluid dynamics (CFD) problems. This trend is accompanied by manufacturers’ needs to
quickly make changes in automotive CFD meshing without time-consuming manual
interactions. TGrid software helps ensure productivity gains at each step, from geometry to
volume mesh. Flexibility and customization allow TGrid meshing tools to be used in a wide
range of applications, from external aerodynamics on Formula One (F1) racing cars to
droplet distribution inside human nasal cavities.

In this generic Formula One car, TGrid
prism layers and HexCore volume meshing
are applied on a high-quality surface mesh.
In this human nasal cavity, wrapper has been
used to produce a valid high-quality mesh
from CAT scan data.

Wrapper Technology
In today’s automotive industry, front-end underhood thermal management (UTM)
represents one of the most challenging meshing applications. TGrid software addresses
this challenge by capturing best practices and automating the time-consuming manual
meshing once required for this class of problems.
The entire underhood wrapper-based meshing process has been encapsulated for
overnight batch execution. Moreover, customized user interfaces can be developed to
expose key parameters and automate specific processes.
Key Wrapper Capabilities
• A full suite of global and local size definition tools using a mixture of curvature,
proximity and fixed- and region-based sizing
• Both manual and fully automatic leak/hole detection and fixing algorithms
