OpenFOAM is a versatile open-source multi-physics simulation toolbox. It can simulate fluid flow (CFD), solid dynamics and electromagnetics (CEM). OpenFOAM was originally developed for Unix platforms, such as Linux, and until now there has not been a method for producing a native Windows version.
If you are one of the lucky few that creates native geometry within a standalone Computer-Aided Engineering (CAE) analysis tool or within a single Computer-Aided Design (CAD) system with embedded CAE analysis tools, then stop reading now. Just a moment though, even if you have embedded CAE tools within your CAD system, but you import geometry for analysis you will still face geometry exchange challenges.
Boundary layers are everywhere. We live within the Earth's planetary boundary layer. Airplanes exploit boundary layers to fly. Golf balls have dimples that alter boundary layer characteristics to maximize their flight time. So what are boundary layers?
Airplanes defy gravity. Formula 1 racing cars corner at incredible speeds generating lateral forces up to 4.5 times that of gravity. Yachts can circumnavigate the globe by wind power alone. These incredible feats are all due to the lift force generated by airfoils moving through air. Of course nothing comes for free; for lift, the cost is drag.
