With practice

Find a good educator, study and work a lot with him for some years.

There are several things spring to the mind,

first you may need focus on one specific tools tutorial, then start making your own simulation. in the meantime, the best tutor could be the mistakes. troubleshooting of mistake could brings you a myriad of invaluable hints. However, studying CFD foundation prior to would be a must.

Dear all,

I can sumarize;

To become an CFD expert, It can be simple with some hardness.

It must know firstly:

1- The fluid mechanics, to be familliar with the equations and types of fluid( Governing equations, laminar-trans-turbulence, compressible and incomprehensible, newtonien...)

2- The numerical methods, to know which methode are better to resolve your problem ( high resolution , first order, simplec....)

After that, you must choose a specialty (Aerodynamics, rehology....), and practice tutorials for any CFD code.

Without forgating the most important thing, the understanding of the physical phenomena.

Mr. Ionut Cristian Scurtu

greeting

There are a many references that can help you to get more experience in CFD and fluent

for fluent you can started with the User guied for any version, and supported by

You Tube where there is a many completed examples that can help you.

before that you must to start to read the references of CFD and that can be find in

1- An introduction to Computational Fluid Dynamics, the finite Volume Method(by: H K Versteeg)

2- the philosophy of CFD can be get it from Numerical Heat Transfer And Fluid Flow by: Suhas V. Patankar

3- Program NATCON: for the numerical solution of buoyancy-driven laminar and turbulent flows in differentially heated...

4- Turbulence Modeling for CFD by:David C. Wilcox

you can find attachment file with title 3D Heat Transfer Problem

I totally agree with Fethi Saidi and Ali Dawood Salman with more stress of studying the fluid mechanics very well

Constant practice. Learn by building your own cfd code for simple problems

I recommend you to read this book and wish you the best of luck

To be an expert, you need to solve as many as you could individual problems that focus on a single solution target.

Later you will just combine the individual problems set up to solve any problem.

Good luck.

Solve many CFD problems you will be expert

Hello,

1. Study fundamental books on Fluid Dynamics.

2. Study about the numerical solution-procedures ( initial value problem and

boundary value problem of the differential equations)

3. Study deeply about Numerical Methods.

4. Study deeply the different programming languages, such as Fortran, C, and

C++ etc.

5. Obtain a good idea on how to discretize Navier-Stokes equation (for Fluid flow)

and other equation using the Finite Volume method, Finite difference method, and

finite element methods.

6. Obtain a good idea on how to generate a grid system for a particular domain of calculation ( your interest).

7. And then solve many problems by implementing appropriate boundary conditions and initial conditions.

8. Obtain knowledge on how to visualize your raw data using other software (

free software: Paraview)

9. Get the knowledge to justify whether your result is correct or not; it is very important!!

10. Study the tutorial manual of a Commercial software, such as ANSYS ( not free) or OpenFOAM ( free)

11. Check how different boundary and initial conditions affect the result of a set governing equation. Different boundary conditions will give you a different solution but governing equations and geometry are the same !!

Finally, you have to repeat the above steps along with other related matter for several months for several problems, which will make you an expert in CFD gradually!! Anyway, it is not so easy to become an expert of CFD for a short time !!

To become an expert of CFD, you have to learn many issues, which are mentioned partially in the above section !! Good luck!!

Reading CFD books, check some tutorials for simulations and than run

Speaking from my experience, the main elements are mathematics, programming, and physics (fluid mechanics at least)!

I am aware that this is really broad and no one can cover the whole but at least one should try to achieve a good level at each one of them.

For mathematics, consider that it is not only about numerical methods, it is also about the theoretical part and even functional analysis. You may find very fascinating shortcuts and overviews of your work if you know more about the mathematics behind your numerical method and your physical model.

Dear Ionut Cristian Scurtu ,

For me, a CFD expert is one who can solve the problems computationally with a precise result. So, he/she must have a good background and knowledge of mathematics, numerical methods, and a particular field such as fluid mechanics, heat transfer, chemistry, and so forth. He/she must do some real projects in industry or other places. Moreover, an expert needs time for having experience.

The process of becoming an expert has curves like a hockey stick.

Have a nice day.

Best regards.

Dear Ionut,

The domain of Computational Fluid Dynamics (CFD) is vast and needs to follow many topics, such as Fluid dynamics, aerodynamics, statistical mechanics and semi-classical transport theory, with emphasis on Navier-Stock and Boltzmann transport equation (BTE). In particular, numerical solutions methods of the BTE should be mastered. As you're already aware of all theoretical background, you just need to get acquainted with the available software packages such as the Ansys CFX program. For a steep-learning curve of Ansys CFX, I recommend to follow webinars and Videos. Please register and get a customer number here: https://www.ansys.com/support

plot and simulate many CFD causes you will be expert in this software and there are a lot of tutorials in you-tube
