Stallion 3D with HIST (Hanley Innovations Surface Treatment) features automatic grid generation and high accuracy for arbitrary 3D geometries. Stallion 3D features solutions of both the 3D compressible Euler and Navier-Stokes equations.
Stallion 3D: Flow past Ahmed Body
The compressible Euler solver (for low speed flows) was used to analyze the Ahmed body geometry for validation of solutions for road vehicles and race cars (F1 for example). Stallion 3D has the ability to read in a complex geometry and provide a quick solution on an ordinary PC or laptop computer under Windows XP, 7 or 8/8.1.
Stallion 3D Workflow and Results
With 700,000 computational cells, the Euler solver computed a pressure drag of 0.254 after 15,000 iterations. This is very close to the experimental results of 0.260.
