Do Less and Accomplish More with Gridgen & Pointwise

Gridgen & Pointwise are 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 aerospace industry, where they continue to earn their reputation for usability and high quality grids, both of which are vital for reliable simulations.

Today both Gridgen & Pointwise are used worldwide in aerospace, automotive, power generation, chemical process and other industries for which CFD is an integral part of the design process.

Hybrid Meshing provides fast turnaround of CFD Projects

Highly complex geometries found particularly in the aerospace and automotive industries can be meshed quickly using our Hybrid meshing tools found in Gridgen & Pointwise.

First the surface is meshed with triangular elements which are then extruded away from the surface to create tri-prism cells suitable for representing the thin boundary layer. The volume between the prisms and the far-field is then filled with tets, including anisotropic tets near to the boundary layer mesh so that the cell size varies smoothly.

Hex wake blocks could also be inserted to efficiently capture trailing vortices and other secondary flow features. Joining structured hex and unstructured tets is done automatically by applying pyramid cells at the interface.
