Abstract

Open Source C++ code is developed for 2D incompressible flow simulation by using vortex methods. The code has modular structure, it permits users to simulate flow around airfoils (as well as around system of airfoils) and compute unsteady hydrodynamic loads acting the airfoils. It is also possible to simulate hydroelastic regimes of airfoil motion in the flow by using weakly coupled and strongly coupled algorithms. Well known vortex methods algorithms as well as original numerical schemes developed by authors are implemented, which makes it possible to raise the accuracy of simulation significantly in comparison to traditional algorithms of vortex methods. It is possible to run simulations in parallel mode, OpenMP and MPI technologies are supported. The source code of VM2D is available on GitHub under GNU GPL license (https://github.com/vortexmethods/VM2D)
