Accurate Aerodynamics and CFD Software
Stallion 3D removes the pain of grid generation. It provides accurate aerodynamics data for your aircraft, automobile and marine designs. The UAV (above) was analyze from a file from GrabCAD.com.

Overview

Stallion 3D is an All-In-One aerodynamics analysis software that performs computational fluid dynamics (CFD) analysis on 3D solid models. The workflow follows these four easy steps:
1. Input your design (eg. CAD Model of your UAV)
2. Size the Simulation (Quick to Detailed)
3. Set Flow Conditions
4. Get the Results (Lift, Drag and Aerodynamic Moments).

Examples
UAV CFD UAV Analysis
Need to analyze your new UAV design? This example shows how easy it is to compute the aerodynamics parameters of your UAV concepts. Just enter the 3D file on your PC to obtain lift, drag and moments.

No Expensive/Difficult Hardware Required
Stallion 3D runs on an ordinary desktop or laptop PC under Windows XP, 7, or 8/8.1 OS. Implementing a full-blow 3D CFD code on a PC eliminates the CPU cost of other options.

Easy Workflow

Stallion 3D features Fast Case Setup (Less than One Minute).

Step 1: Import the CAD geometry in .stl format

In this step, you can rotate or scale the geometry to match your inputs.

Step 2: Size the Simulation

Step 3: Enter the flow speed and angle of attack.

Flow Solvers

Stallion 3D solves the 3-D Euler or Navier-Stokes equations using an automatically generated cartesian grid. The grid detects the immersed boundaries and provides accurate solution without user intervention.

Features of Stallion 3D include:

  • 3-dimensional compressible Euler & Navier-Stokes equations using a finite-volume solver
  • 1st and 2nd order flux vector splitting
  • 4-stage Runge-Kutta time marching scheme using local time steps
  • Automatic cartesian grid generation for arbitrary multiple body placement.
  • Low and high speed solutions
  • Plots of pressure, Mach number, temperature & total pressure
  • Surface plots of Cp, Mach number, velocity ratio & temperature
  • Computation of overall lift, drag & moment coefficients about arbitrary locations on and off the bodies.
  • Computation of lift, drag & moment coefficient for each shape.

Validation

Validation for the Onera M6 wing test case is performed using the Euler equations solver. Stallion 3D solves the problem with a coarse grid (440,000 cells) and a fine grid (1.6 million cells). This classic validation case is run at a Mach number of 0.84 and an angle of attack of 3.06 degrees.
