Flow over a cylinder

Finite volume method: The finite volume method (FVM) is a method for representing and evaluating partial differential equations in the form of algebraic equations. In the finite volume method, volume integrals in a partial differential equation that contain a divergence term are converted to surface integrals, using the…

AIM: To simulate an incompressible-laminar-viscous flow through the backwards-facing step geometry.  Two cases are given: Case 1 - Simulate the flow without using any grading factor (i.e., GF = 1) Case 2 - Simulate the flow with a grading factor of 0.2. The cells should be finer near the walls (including…
