Hi all,

I want to learn cfx in deep.But I can only learn from the Help.There is no efficient transient simulation tutorials ,that I need most.What should I do next?

Thank you in advance for any suggestion. Regards,James

hi, tutorials are available. you can learn a lot from them. Infact I did like that only. best wishes

I am completely new in CFX. As I undedestood, this is completely different with fluent and ansys.
My understanding is that the geometry and mesh should be prepared in other softwares. Am I right? How can I use the Ansys model and mesh in CFX?
Please inform me if you have any recomendation. (m.shahverdi@gmail.com)

Hi ,
I'm also new to CFX and I have a lot of troubles to get started ! So if you find any helpfull tutorials/manuals please share it with me .

Mahdi ,
You may create the geometry and the mesh using DesignModeler and DesignMesh that are available on ANSYS Workbench .
You can also create geometry and the mesh using GAMBIT , insert it into FLUENT and create CASE FILE . Then insert the FLUENT CASE file into the CFX .

There are good tutorials in the software. Also, there are tutorials in the Program Files. For me, the directory path is
C:\Program Files\ANSYS Inc\v121\commonfiles\help\en-us\CFX\help\pdf

I would suggest googling "CFX tutorial" and "DesignModeler tutorial." There are even hits for youtube but I have not checked them out.

CFD is hard core stuff and requires quite the learning curve. Good luck!

hi
I think the best reference to learn a software is its help along with tutorials. to do a good simulation using CFX, I think you shoud study modelling guide along with theroy guide, because it is important to be inform of different models that are available in CFX.
And about mahdi's question, I use gambit to build and mesh the geometry. In this way, you should choose the generic solver in gambit, and export the file with a "*.neu" format. import the file in fluent, check the mesh, initialize it, and then export it to a "PATRAN neutral" platform. in cfx you should import the mesh from the "PATRAN neutral" option and with a ".neu" format.
good luck

In addition to the CFX tutorials, which are very good and are included in the Help file, I'd recommend purchasing, downloading (if you or your school has a subscription to Springerlink, Knovel, etc.), or signing out a CFD theory textbook. CFD Online has a section with CFD book reviews [http://www.cfd-online.com/Books/ here]. Computational Methods for Fluid Dynamics (Ferziger & Péric) is my book of choice.

If you don't know the theory, you will be wasting your time and your results. I wasted almost an entire summer doing CFD simulations without knowing the theory very well. I like to read while my simulations are running. Don't make the same mistake I, and many others, made.

Help file is cool okay
but any samples ?!
I think Samples + their pdf tutorials are the best sources to learn a CFD software
like those are available for fluent !?

[ghorrocks]

There are a lot of tutorials available on the ANSYS Customer web page on the ANSYS web site.

The examples are located in the Help file as well as on the ANSYS Customer Portal.

You have to start Workbench, create your analysis(a list on the left side). use Design modeler to import geometry file(Parasolid, for example) use meshing to create mesh and use CFX-Pre to apply boundary conditions.
