Short summary

Feasibility of a freely available CFD tool, OpenFOAM, in calculating flows of general relevance to the wind industry is investigated by comparing several aspects of its performance to a well-established in-house EllipSys3D solver. The comparison is focused on CFD solver demands regarding grid generation process and computational time. The quality and accuracy of the achieved results are investigated by conducting the computations using identical/similar solver parameters and numerical setups..
