Gridgen - Reliable CFD Meshing Software

Gridgen is Pointwise's classic software, used by engineers and scientists worldwide since 1984 to reliably generate high quality grids for engineering analysis.

Learn how your CFD can benefit from Pointwise meshing software by trying the software for yourself.

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.

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.

Just because there's a new horse in the barn doesn't mean we're sending Old Reliable out to pasture.

A customer once said, “For real work, you use Gridgen.” That's because it's known as the powerful CFD workhorse. Gridgen fans will tell you that's still true, although many have new-found loyalties since the release of Pointwise, our next generation software.

But die-hard Gridgen fans don't have to worry. Old Reliable is not going away and our license lets you run both products. That means you die-hards can try Pointwise. You might be surprised to find yourselves with a new favorite, once you experience its short learning curve and superior features.

License Once, Get Both

Don't forget - when you license Gridgen you get our next-generation meshing software, Pointwise, at no extra cost. You choose which one to use based on your meshing requirements and your preferences for interface and workflow.
