Stallion 3D 4.0 is the most powerful CFD software available for professional aerodynamicists and multidisciplinary engineers. 3D grid generation is completely automatic and complements an agile design-analysis process. Its novel CFD algorithms solve the 3D compressible Reynolds averaged Navier-Stokes (RANS) equations directly on the STL geometry. The Stallion 3D workflow is completed in a matter of seconds and produces high fidelity results in just hours. You will literally solve your design problem today.
Stallion 3D 4.0 is the only software with automatic 3D grid generation, turbulent Navier-Stokes equations (RANS) solutions that runs on your laptop or desktop PC. It outputs accurate aerodynamic coefficients (CL, CD & CM) for your actual geometry.
Stallion 3D 4.0 requires MS Windows 7, 8 or 10 (64 bit).

Start your aerodynamics analysis by importing your 3D CAD model (STL format) into Stallion 3D. Actual Geometry Analysis (AGA) eliminates the time spent to de-feature your design. Stallion 3D analyzes your actual design even with small features such as nuts, bolts and logos.
Stallion 3D unique CFD algorithms solves the 3D compressible Euler, Navier-Stokes and Reynolds Averaged Navier-Stokes (RANS) equations. Grid generation is integrated into the solution process and is automatic to the user. The HIST (Hanley Innovations Surface Treatment) algorithm solves your 3D CAD model using the most accurate and efficient methods in CFD.
From your inputs of velocity, side-slip and rotations, Stallion 3D computes the CL, CD and moment coefficients (Pitch, Roll & Yaw, CMx, CMy & CMz) for your design. In addition the the exact magnitudes of Lift, Drag and Moments, Stallion 3D generates plots of pressure, speed, density and temperature using its built-in presentation tools.
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). Read Article.
Stallion 3D receives excellent results for the inviscid analysis of the Onera M6 wing. The article shows comparisons made with experiments for two grid settings. Read Article.
Analysis of a Cessna 210 using Stallion 3D Euler solver. The number of cells is 700,000+. The full range of angles of attack was performed within 24 hours on a laptop computer using multiple instances. The STL for this study was obtained from NASA's OpenVSP.
The DrivAer experiment is a validation exercise for CFD solutions of passenger cars. The picture shows the flow velocity near the surface of the DrivAer model with mirrors and detailed under body. The problem was analyzed in Stallion 3D using 1.7 million cell and the RANS/k-epsilon solver. The solution was unsteady with an average drag coefficient of about 0.29.
The results from Stallion 3D 4.0 RANS solver (CL = 0.41, CD = 0.25 & CM = -0.0387 ) were compared to the findings of NASA Technical Memorandum 4117,Transonic Aerodynamic Characteristics of a Proposed Assured Crew Return Capability (ACRC) Lifting-Body Configuration by George M. Ware. From the graphs, the corresponding experimental results were (CL = 0.48, CD = 0.24 & CM = -0.042). The geometry was obtained from NASA OpenVSP. The flow parameters for this case are M = 1.2 with an angle of attack of 12 degrees. This simulation used about 480,000 cells and ran for 3 hours on a 2 GHz laptop computer.
