Free CFD is an open source computational fluid dynamics (CFD) code. You can learn more about it on the about page. Some key features are:

• Written in C++
• Easy to use, easy to code
• Density based Navier-Stokes solver
• All speed ( We know that this is too general a statement but let’s say the code can handle a Mach number of 3 as well as 0.001)
• Parallel ( MPI )
• 3D Unstructured grids of mixed element types (Hexahedra, tetrahedra, prism, pyramid)
• Fully implicit time integration

The code is not released yet. But expect a release really soon.

The code is in early its early stages of development. It is in the process of being well validated and well documented. But the important thing is the idea: 

We want to extend the open-source ideology to CFD community with an easy-to-use, easy-to-understand and easy-to-develop code. We hope this project to be a sustained effort,  very dynamic in its development, driven by your feedback, friendly and responsive to you. 

By the way, we are both PhD students at the University of Michigan, Aerospace Engineering Department. 

You can submit to our feed for the first release announcement.
