VM2D: Open Source Code for 2D Incompressible Flow Simulation by Using Vortex Methods

The article describes an open source C++ code we have developed for 2D incompressible flow simulation using vortex methods. The code has a modular structure, and allows users to simulate flows around airfoils (also, around a 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 and strongly coupling strategies. The software implements well known algorithms and also original numerical schemes developed by the authors, thereby significantly increasing the accuracy of simulations compared to traditional algorithms. The software makes it possible to run simulations in parallel mode; OpenMP and MPI technologies are supported.
