Here looks a right place for this question.

What's the difference between Finite difference(FD), Finite Volume(FV), FEA(Finite element analysis) ?

Thanks for inputs.

To answer your question, try to read chapter 3 of Shaw, C. T. book "Using Computational Fluid Dynamics", 1992. Its very fundamental book in CFD.

I think most CFD books will tell you about FD, FV and FEM. Ferziger, J.H., Peric M.: Computational Methods for Fluid Dynamics, 1996 is a famous CFD book. It also has some simple programs. (no use for practical problems)

I agree Yangang and I advise you to "Ferziger, J.H., Peric M.: Computational Methods for Fluid Dynamics, 1996 "

Hi. The difference is in the way that you discretized the partial differential equation. FD is the Finite Difference Method FV is the Finite Volume Method FEA is the Finite Element Analisys

Good luck
