[CFD] The Finite Volume Method in CFD

[CFD] The Finite Volume Method in CFD

An introduction to the second order finite volume method that is used to discretise the terms in the Navier-Stokes and other scalar transport equations. This approach is adopted by many mainstream CFD codes (OpenFOAM, Fluent, Saturne). The following topics are covered:

1) 3:38 How does the finite volume method work?

2) 8:85 What are implicit and explicit treatments?

3) 13:04 What special treatment is used for the convection and diffusion terms?
