High-fidelity, High-productivity CFD Simulations of Airflow over a Golf Club Head

The simulation of airflow over a golf club head will be used to demonstrate the complete CFD process from geometry creation through solution post-processing. Intelligent Light will show how FieldView and CFD Data Management techniques bring complex simulation data to actionable information. Two different types of hybrid meshes are created; one is made exclusively in Pointwise, highlighting its anisotropic tetrahedral extrusion (T-Rex) meshing technology, and the other combines Pointwise with mesh generation tools developed at UTC SimCenter. Steady and unsteady CFD solutions are computed on a distributed memory LINUX compute cluster with TENASI, a UTC SimCenter parallel-unstructured Reynolds averaged Navier-Stokes code. Post-processing the results is performed using FieldView by Intelligent Light, revealing the complex features of the flow, comparing the results of the two methods, and creating a highly productive workflow that can be used for subsequent studies. A CFD workflow will be demonstrated that is efficient and productive for the large volumes of data seen in complex, unsteady CFD. Overall, this webinar will illustrate the various steps of the complete CFD process typically followed in aerodynamic analyses of realistic geometries.

Topics covered will include

  • Using Pointwise for hybrid mesh generation
  • Combining Pointwise with UTC SimCenter's tools to make hybrid meshes
  • Distributed-memory, parallel CFD computations using UTC SimCenter's TENASI Navier-Stokes solver
  • Understanding complex flow features and deriving actionable information using FieldView in a high-productivity CFD workflow
