Simulating the fluid flow through a backward facing step using the icoFOAM solver

Objective: In this project, we observe the distinct differences between different graded meshes,following the grade factors of 0.2,0.5 and 0.8 along the length of a backward facing step. The blockmeshdict file for the same will be displayed below. The grade factor for the wall is kept at a constant 0.2. For the sake of clarity, the…
