Stallion 3D 4.0 is the leading 3-dimensional analysis package for aerodynamics professionals who design and build UAVs, fixed-wing aircraft, ground vehicles and racing yachts. The software solves the full 3D compressible Navier-Stokes and Euler equations on a Microsoft Windows laptop or desktop computer. Grid generation and post processing are automatic and fully integrated into the solution. Stallion 3D analyzes your 3D designs within your workday. We call this SameDayCFD. Results from Stallion 3D match experiments. The software is powered by your personal computer and there are no additional codes or fees needed to obtain accurate solutions.
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 the Bell X1 Aircraft using Stallion 3D. The number of cells is 400,000+. The angle of attack is 1 degree and the speed is 420 meters per second. The problem was solved from CAD to final results in 3 hours on a 2 GHz laptop.
Analysis of a MIG 15 using Stallion 3D RANS solver. The number of cells is 700,000+. The angle of attack is 15 degrees and the speed is 100 meters per second. The problem was solved from CAD to final results in 8 hours on a 2 GHz laptop. The CAD file was obtained from NASA's OpenVSP.
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.
This F1 model was analyzed in ground effect using Stallion 3D. 1.7 million cells were used in the simulation on a 2 GHz laptop PC. Stallion 3D used used it RANS/k-epsilon solver with a wall function boundary condition.
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 underbody. 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.
Stallion 3D 4.0 requires a MS Windows Laptop or workstation running the 64 bit versions of MS Windows 7, 8 or 10. A 4 core PC with a clock speed of at least 2 GHz is recommended for using the software.
