I need start to realize computational fluid dynamics but I dont know wich will be the best software to begin. Doing a quickly search on internet I have found some software like Autodesk and SolidWork but I would like to know if exist any more specialized or which one is better, Thank you.
Dear Oscar May Tzuc
Ansys is the software which can b used for CFD . In Ansys workbench13 or above version you can use module of CFX and Fluent for CFD . you can find tutorials of ansys easily from youtube and cfdonline.com
Dear Oscar, Abdul share the same opinion than mine. Ansys is the most complete software for CFD. Just completing his answer, the version Workbench 16 you have a more simple and intuitive configuration of parameters.

depending on the type of problem you want to simulate you need to choose the CD tool. Some tool have specialized modules for some particular problems. So Choose Wisely.
I suggest OpenFOAM. Well documented. And you can read the code completely.
If you have good knowledge of Numerical Methods already and are interested in discovering the essence of various terms used in equations, then you can start with Fortran Programming or OpenFOAM. As every physical process can be seen as a set of equations. Most Scientific people use FORTRAN for their simulation. Mostly, industry people or less involved persons use ANSYS (software based CFD) only.
If you are trying to acquire an in-depth understanding of fluid mechanics, I think that you should go with developing your own program codes that solve discretized equations of mass conservation, momentum conservation, etc. Research of this kind is easier to publish (at least in my humble experience). If you choose to develop your own code, I recommend Fortran.
Best regards,

Dear Oscar May Tzuc,
Autodesk and SolidWorks are not CFD-Software, but CAD-Software. If you really want to get into learning CFD and know how to code or want to learn it, you could develop your own code. But this takes some time and effort. If you want to take a shortcut, you can use OpenFOAM. Most necessary CFD code is already implemented, it is highly adjustable and free of charge. But the use of this software is not quite beginner-friendly. If you want to start right away and need results in a short time, I would recommend to use commercial CFD-Software like ANSYS Fluent/CFX or COMSOL.
Good luck and best regards!
I am truly greatful for yours anwers wich have helped me to clear several doubts. Now I have an idea about the diference of the diferents softwares and could gide by the best way my work.
Thak you.
Hola, yo estoy utilizando OpenFOAM, veo que ya te lo sugirieron, es software libre y está bien documentado, trabajas desde una terminal de Linux y tiene un visualizador bastante bueno.
Hello, please have a look at this library:
www.sparselizard.org
It is a rather new but rapidly developing library. It is a general nonlinear multiphysics c++ FEM library, fully free and open source. The main feature is that it is general, extremely concise, easy to use and fast/multithreaded from a to z.
Just recently examples have been added (and of course validated) for creeping flow and incompressible laminar flow, static and transient. In the coming months compressible flow examples and turbulent flow examples will be added, on large 3D meshes.
Should you want to simulate problems that are not in the examples there is no big limitation in what you can do if you know the equations.
Please do not hesitate to support emerging open source FEM software.
Regards.
Hello Oscar,
Actually it depends on your condition, if you are the beginner for CFD engineer, and you need a short and simple guide then you can choose the commercial software such as ANSYS, STAR CCM+,etc. But you have to spend a budget for buying the tools. Otherwise, you can use the OpenFOAM with free of charge but you have to effort to learn the code inside or you are familiar with C++ language. So be wise to start your CFD tools.
Cheers,
