Presenters will be Pointwise's Travis Carrigan and Mark Landon from Optimal Solutions.

Easily define shape deformation control points using Sculptor.

Export grid and boundary conditions in native OpenFOAM format.

Save time by directly examining grid quality metrics within Pointwise.

Generate a high quality surface and volume mesh using T-Rex.

Quickly clean up and organize dirty CAD using Solid Meshing.

Also, all tools have been coupled to form an automated optimization framework making it possible to find the subtle shape changes that produce large improvements in design performance. Even for large deformations, this technology can maintain surface boundary layer thickness and orientation.īy eliminating the requirement to remesh after each volumetric deformation, solution changes are minimized and primarily subjected to the changes seen by the OpenFOAM flow results due to model differences. A technology called Arbitrary Shape Deformation is used to smoothly morph the nodes of the mesh that are inside of the volumetric deformation space. Using the DrivAer mesh, we define a set of volumetric shape deformations using few design variables within Sculptor.

Using this geometry, we demonstrate a technique called Solid Meshing to heal faults in the geometry and recover the original engineering intent and when coupled with T-Rex (anisotropic tetrahedral extrusion) enables automated, high quality volumetric grid generation. The case study for this work is the DrivAer model developed by the Institute of Aerodynamics and Fluid Mechanics at the Technische Universität München. To demonstrate this, we introduce a collection of best practices for cleaning complex analytic CAD encountered in the automotive industry and demonstrate a robust meshing technology in Pointwise that can automatically generate high quality boundary layer resolved meshes that retain their quality when morphed by Optimal Solutions' Sculptor during the optimization process. High quality meshing coupled with robust shape deformation techniques enable large design space exploration for optimization without the need to remesh the geometry.
