AIM  To explain the working of the Finite Volume Method (FVM) and its major differences as compared to the Finite Difference Method (FDM).  To explain the role of different Gradient Schemes and Interpolation Schemes along with the significance of Flux limiters.  THEORY  In computational fluid dynamics,…

AIM Simulate an incompressible-laminar-viscous transient flow through the backward-facing step geometry. Perform 2 case studies as described below and compare the results. 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…
