The global trend towards urbanization has increased the popularity and the number of studies in the field of urban physics. Computational Fluid Dynamics (CFD) is one of the tools that can help researchers to investigate the effect of urban microclimate on comfort, health and energy demand. In this study, CFD simulations of the wind flow in a generic urban configuration are performed with a commercial (ANSYS Fluent) and an open source (OpenFOAM) CFD solver. The 3D Reynolds-averaged Navier-Stokes (RANS) equations are solved in combination with the standard k-e and the realizable k-e turbulence models. Results showed that both of the solvers were fairly good in predicting the wind velocities at the area of interest. Compared to the wind tunnel measurements, the simulations predicted wind velocity ratios with a correlation coefficient of 0.76, 0.77, 0.75 and 0.74 for ANSYS Fluent standard k-e, ANSYS Fluent realizable k-e, OpenFOAM standard k-e and OpenFOAM realizable k-e respectively.
