Overset Grid Assembly Tool Comes to Pointwise

Streamline the workflow of overset grid assembly meshes.

The newest release of Pointwise’s CFD meshing software will feature overset grid assemblies and direct integration.

Overset gridding allows users to overlay grid block components. This will bypass the complex generation of point-to-point, abutting and multi-block grids. To ensure the overset grid will work, however, users will need to ensure that the overlap of the grids is sufficient for data to be shared between them.

The overset grid assembly software computes the overlap without the typical collection of tools used by engineers to patch them together. Integrating the tools into Pointwise allows for a more efficient workflow.

“The integration of grid generation and overset grid assembly represents a vast improvement over the hodgepodge of disparate tools typically employed by practitioners of overset CFD,” said Nick Wyman, Pointwise Director of Applied Research.

“What we are releasing today for production use,” said Wyman, “is the result of a multi-year research effort Pointwise conducted with funding from the U.S. Air Force’s Arnold Engineering Development Complex, Air Force Materiel Command. That research was followed by a full year of fine-tuning in preparation for release to all our customers.”

John Chawner, Pointwise President said, “Pointwise has been a proud, long-time sponsor of and participant in the bi-annual Overset Grid Symposium … This release of Pointwise helps us continue our integral relationship with that community.”

Other features in this release include improved:

  • Support for NX files, STL, ANSYS Fluent and PLOT3D
  • T-Rex, anisotropic tet-extrusion and hybrid mesher
  • User interface
