Code for most powerfull FDV Method
 

Dear Sir / Madam/Friends

SUB:DEVELOPING SCIENTIFIC ALGORITHMS FOR THE MOST POWERFUL COMMERCIAL UNIFIED CFD METHOD ENGINEERING SOFTWARE PACKAGE BASED ON THERMO-FLUID FLOW FIELD DEPENDENT VARIATION (FDV) THEORY.

. During my M.Tech (Thermal Engineering) course, I have carried out project work titled " Grand Unification of CFD methods to Resolve and Characterize Multi-complex Physical phenomena in Thermo-Fluid Dynamics". This project work was primarily focused on the very special and powerful FLOW FIELD DEPENDENT VARIATION (FDV) method .Most of the currently available computational schemes in finite difference method (FDM), finite element method(FEM) and finite volume method(FVM)can be generated as special cases of FDV method for computational solution to every thermo-fluid flow physical phenomena.

I have have keen interest to be a part of R & D team of an organization for developing scientific algorithms for commercial Unified CFD method engineering software package based on FDV theory. With the arrival of such commercial Unified CFD method engineering software package based on FDV theory, does the existing commercial CFD Software engineering package/tools like FLUENT, CFX, ANSA, STAR â€" CD, ICEM â€"CFD, TGRID, PROSTAR will face stiff resistance in the commercial market ? This depends on upon how extensively and rigorously future research on Unified CFD method via FDV theory is carried out . I want to know is there any organization whose R & D activities is shifted toward Unified CFD method via FDV theory for enhancing their future business by developing most Power full Commercial Unified CFD Method Engineering Software package.

. In this regard, presently I am making earnest efforts to contact reputed organizations involved in developing / utilizing existing commercial CFD Software engineering package/tools to present the superiority of FDV method over the current prominent CFD methods/ schemes. Till yet there no response.

So I want know the right platform where I can present my idea of developing such a power full commercial unifiedCFD package so as have commercial benefits or a prospect employment

Thanking you,

With Warm regards

That's a whole bunch of hype your peddling. Do you have any data to back up those claims?

Are you also planning on feeding the entire world, creating world peace and solving global warming too?

Re: Code for most powerfull FDV Method
 

Thanks for the information. I will refer to the last one in your list, the book by Chung, as readers of this forum can go through it using the google book shelf. As you see, the FDV is a unified approach to develop discretised formulas for the Finite difference method, as you might well know, the FDM is used in some specialised codes, but not in general purpose codes which are following the FV method. Why? 1- You have to deal with real world geometries not idealized academic problems. 2- You have to preserve the physics of the problem. 3- easy to code (less bugs) Your enthusiasm is well appreciated, but you need to get closer to real world situations. Good luck and keep up your enthusiasm

Re: Code for most powerfull FDV Method
 

Actually, if you take a closer look at Chung's book, you will find that the FDV method is an expression of the Navier Stokes equations that is applicable to finite difference, finite element, or finite volume discretizations. The FDV finite difference formulation is described in section 6.5. However, the finite volume via finite difference formulation is in section 7.4, the finite element formulation is in section 13.6, and the finite volume via finite element formulation is in section 15.2.2(4). The theory looks promising, however I have not look deeply into its validation. If I can find some time (very rare with work and two kids these days), I might look into it further and post some comments here and on clusternut.net.
