Watch this video to find out how to use Stallion 3D to analyze
your OpenVSP models.
Stallion 3D is the Easiest and Most Cost Effective Solution for
Aerodynamics Analysis of 3D Designs. It eliminates the grid generation step
in the fluid dynamics analysis. The software imports your 3D design and accurately computes lift, drag and moments for both
air and water analysis.
Stallion 3D requires Windows XP, Vista, 7 or
With Stallion 3D, it does not take forever to find out facts about your project.
Conceptual aerodynamics analysis is no longer limted to simple geometries and simple flowfields. This means that
students can complete an interesting assigment within a week. Semester projects can be researched in a realistic learning
scenario. Designers and engieers
can know the workings of a concept before moving forward to the next stage.

Race Car Spoilers From CAD Models
Stallion 3D is the perfect tool to
test wing and spoilers for race cars. The program saves time and money since
testing of spoiler designs can be performed on the computer before building
an expensive carbon fiber prototype.
