Stallion 3D: CFD for Aerodynamics
User-friendly high fidelity CFD software for aircraft, UAV, sail, hydrofoil and rocket aerodynamic analysis.
Stallion 3D fills the gaps between low fidelity surface panel methods & expensive cloud based CFD apps. It solves the compressible Navier-Stokes equations for subsonic, transonic & supersonic flows. Upfront aerodynamics is accurate and accessible with built-in automatic gridding. Stallion 3D is the only 3D aerodynamic tool that has our proprietary technology to ensure your success.

Real‑world validation
HIST (proprietary) + RANS/k‑epsilon for credible engineering results.
Passenger car drag
DrivAer with mirrors and detailed underbody. Stallion 3D used a ~1.7M cell RANS/k‑epsilon setup; unsteady solution with average drag coefficient near 0.29.
Supersonic lifting body
HL‑20 at M=1.2, AoA=12°: results compared to NASA TM 4117. Example case ran ~3 hours on a 2 GHz laptop (about 480k cells).
Transonic wing
ONERA M‑6 wing at M=0.84, AoA=3.06°. Comparisons shown against published data and NASA CFL3D reference results.
Who uses Stallion 3D?
From startups to classrooms to established R&D teams.
- UAV & eVTOL startups needing credible aero data without a full CFD department
- Aircraft & rocket designers iterating on concepts before committing to big campaigns
- Universities & educators giving students hands‑on 3D RANS CFD on classroom PCs
- Consultants & small teams who want full‑body CFD with predictable local compute
