Studies of flow over a square cylinder have been worked upon extensively, not to just understand the flow physics but also the forces that act on the body and the reactions that the body experiences. Inspired by the past studies, this work focuses on the computational aspect of it. The amount of dependency of results on the meshes is very well known, therefore, both the problems were combined together to study several mesh strategies for flow over a square shaped cylinder. Three meshes were designed and calculation were carried out using RANS Navier Stokes Equation. The best strategy was then chosen and grid independence study was done. The best mesh was then selected and the flow visualization work was carried out. All the numerical simulations were done using open-source software package OpenFOAM.
