Open VOGEL is an open source framework intended for the simulation of aerodynamic problems through the Unsteady Vortex Lattice Method and first order singularity panels (vortex rings, flat doublet panels and flat source/sink panels).The code has been fully developed in the .NET framework using Visual Studio Express and it is published under General Public License, GPLv3. The idea behind this way of working is that those who use the software for practical applications can directly benefit from what researchers are achieving, so that their results can be directly put into practice.
