I have just studied basics of CFD from J. D. Anderson's book and I want to start simulating in a platform like Fluent. Can anyone tell me how to start?
I think the important thing at learning any software is not to get stuck doing tutorials. Do one or two of them, to get to the very basics, then switch to real problems. There your motivation will be greater and you'll learn much faster, although it may look as a harder way to do it. I usually give my students a Fluent crash course in 3 hours, then I "throw them into water and let them swim alone"...
As you have already studied the basics of CFD ,you got an clear idea about the logic applied in CFD computation.In Ansys Fluent software you have to first draw the design of your field of study, then you have to fixed the boundary conditions and constrains according to your problem,then you have to insert material used and its properties and you have to run the program for your problem.As for example, if you want to analyze the heat transfer from flat plate or in an pipe, you have to draw a flat plate or a pipe with the help of the basic cad[ inbuilt inside the Ansys software] in the Ansys workbench.You can also import drawing from done in other design softwares such as Auto cad.Solid Works etc(It contains all the extensions for other file format) in the workbench.After that,You have to fixed the boundary conditions and have to give the properties of the materials .Then you have to run the software to visually analyse your problem solution. All the boundary conditions and properties of materials are already embedded in the software. Further,If you know about programming then you can write a program for your work and save it for future use.
You can go for youtube and other e-resources for online video tutorial.

Yes i agree with matevz dular , you just staring with some tutorials like as available in the cornell university site. Do three out of them like one from 2d and one from 3d and third one you can choose any problem over their and try to solve your own way. So in this way you will definitely learn how to play with cfd software. rest if you will face any problem or need suggestion feel free to ask & if you need books or tutorials then i will provide you but now important thing is just give your 1day to cfd .
I too am starting to learn FLUENT (Version 13.0). I downloaded the User's Tutorial Guide and it asked me to download a file called introduction.zip in the first problem from the User Services Guide page. But I am not able to open the hyperlinked page.
While going through the Fluent tutorials (which are very helpful), we still need to master the underlying formulation and principles in order to accurately apply the Fluent to our problems. Also, take note of the various assumptions and simplifications deployed in most of the tutorials. Good Luck.
A simple tutorial (such as one in the aforementioned Cornell University simulation Cafe site) can help get familiar with the software interface and the basic CFD solution procedure. Further improvement will need knowledge of CFD theory (such as an introduction of CFD from Anderson's book) and the detailed structure of the software itself. The user guide of the software (Fluent, ANSYS, or STAR-CCM+) would be the best source for mastering the software for various simulation and modeling. You can learn how to simulate by following the tutorials in the user guide and for how to model by understanding the documentation in the model section. Modeling new flow phenomena also require knowledge in the related application area.
