What is Stallion 3D with HIST - exactly?

What is Stallion 3D with HIST?
Stallion 3D is a fully automatic, All-In-One, software package for analyzing 3D complex geometries in  fluid flows (gas or liquid).  The software allows you to perform aerodynamics analysis  on just your laptop or desktop computer.  It employs a novel computational fluid dynamics (CFD) technique that solves the fluid equations and produces plots of pressure, velocity, Mach number and temperature. The software also computes the lift, drag moments and related forces acting on your 3D CAD geometry.

What is HIST?
HIST is the acronym for Hanley Innovations Boundary Treatment. It is a propriety CFD technique that applies the flow boundary conditions to arbitrary geometries immersed in a Cartesian Grid. HIST can handle both inviscid and viscous (no-slip) boundary conditions.  It can be used to solve subsonic, transonic and supersonic flow problems.

Why is the program referred to as an “All-In-One”?
Stallion 3D does not require the purchase of additional software for pre- and post processing. . It handles everything from reading in a CAD model to graphing and tabulating the results of your aerodynamics/CFD analysis.

Is HIST similar to other grandfather or newer CFD solvers on the market freeware?
The HIST solver is entirely new and robust enough to capture shock waves and analyze viscous flows.

Is Stallion 3D with HIST,  an interface software,  to use with pre-existing Cartesian software program?
It is not an interface program. It is an All-in-One aerodynamics & CFD program for analyzing CAD geometries in a flow field.

How long does it take for someone to setup a problem for analysis in Stallion 3D? 
Setting-up,  literally, takes.... just seconds. 

Do I have to mesh a grid at any time?
Stallion 3D specifically eliminates the need for our customers to grid because of HIST, our invisible meshing feature.

Do I need to purchase a pre-processor or mesh generating software for  Stallion 3D?
No. Grid generation is built into Stallion 3D.

Do I need to purchase a separate solver to analyze the geometry?
No. It is built-in already in Stallion 3D. Stallion 3D is equipped with algorithms to solve the full 3D compressible Euler & Navier-Stokes equations.  The analysis is valid for low and high speed flows of liquids and gasses.

Do I need to purchase post processing or separate graphic package to see the graphics after the simulation is finished?
No.  It is built-in already in Stallion 3D.

What are the workflow steps for Stallion 3D? 
1. Insert watertight CAD picture. (takes just a few seconds)
2. Add your parameters (Flow speed, angle of attack, ground effect or rotation  take just a few moments to specify in Stallion 3D.)
3. Stallion 3D will fully and accurately mesh and set-up your grid and begin the analysis.
4. Once the flow is analyzed, the program will automatically have your results ready for you to view or save.

Hardware Requirements?
Laptop running the 64 bit version of Windows XP, 7 or 8 (8.1).

Does the program use a cloud to run simulations?
We do not use a cloud for running simulations. You can do all of your work on your laptop.

What is the general maximum number of cells that can be run for a Windows  simulation?
2.5 million cells.

What are the current prices for Stalllion 3D with HIST as of July 2014?
Please visit for current prices.

How soon do I receive the Stallion 3D after ordering?
The same day.  Please call us at (352) 240-3658 or visit to place your orders.

If I purchase the popular 3 month lease subscription, can I apply what paid for the 3 month lease to a 12 month lease?
You can upgrade to  a 12 month lease, with the 3 month credit.
