Gridgen

Gridgen is a complete meshing toolkit used to generate three-dimensional (3D) grids for complex geometries in a production environment, often where CFD is mission critical. The software`s origins are in the demanding U.S. aerospace industry, where Gridgen continues to earn its reputation for usability and high quality grids, both of which are vital for reliable simulations. Today Gridgen is used worldwide in aerospace, automotive, power generation, chemical process and other industries for which CFD is an integral part of the design process. Examples of where Gridgen is being used can be found here.

What does Gridgen do?

Gridgen generates structured hex, unstructured tet, and Hybrid meshes...
Interfaces with overset grid assembly software...
on CAD data without requiring repair...
and exports meshes in the native formats of many CFD and other solvers...
while running on Windows (Intel & AMD), Linux (Intel & AMD), Mac, and Unix.

What makes Gridgen special?

The T-Rex method for rapid, high-quality generation of hybrid boundary Layer meshes represents the leading edge of meshing technology.
The meshes it generates are of high quality leading to more accurate solutions and faster convergence.
It`s easier to learn, use, and remember how to use than other meshers and includes a scripting language so that you may customize the software for your purposes.

Important! Before performing a complete installation of the latest version, you should uninstall or MOVE any pre-existing installation to a new directory.
