Gridgen is our flagship product. It is the meshing software used by engineers and scientists worldwide since 1984 to reliably generate high quality grids for engineering analysis.

What does Gridgen do?

Gridgen generates structured hex, unstructured tet, and hybrid meshes...
on CAD data imported from its native files and without 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 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.
Technical support is promptly provided by engineers with industry experience who understand how CFD can impact the design process.

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.

Do Less and Accomplish More with Gridgen

Gridgen increases the value of CFD simulations by reducing the effort required to generate high quality meshes. Its techniques for acquiring and "repair-free" meshing of sloppy CAD models, automated high-quality grid generation, and portable ease-of-use combine to make Gridgen an integral tool for engineers who require reliable computational simulations.
