By using icoFOAM solver in openFoam to simulate the flow through a backward facing step

Objective: Aim Create a velocity profile at the 0.085m distance from the inlet domain Number of cells along the x direction= 200(Whole Domain) Number of cells along the y direction = 10(Whole Domain) Use a graded mesh. Grading factor near all walls should be 0.2,0.5 and 0.8 so here we are dealing with three cases of different grading…
