snappyHexMesh tutorial for beginners- Flow past objects

Hello all!!! In this tutorial, I briefly explained how to use snappyHexMeshing in OpenFOAM. I also briefly discussed how to make your models with FreeCAD (Free open-source software) for making your object file and export it to OpenFOAM for meshing. This tutorial is mainly for beginners. Screencast recorded in Ubuntu 16.04 with KAZAM. I am thankful to OpenFOAM, FreeCAD, and MeshLab community.
