Hi all! I'm new at FLUENT. Could you give me advice? I can't import mesh from CFX (File\Import\CFX\Def. file). What do you recommend? Message is following. 'Error: bad syntax. Usage: utility fe2ram dimension read_format zoning write_format [inputfile [outputfile]]

dimension: [-d2 | -d3 | -surface]

default is -zGROUP.

What version of Fluent are you using? There is an option in the Fluent-Beta (12.0.3) to import cfx definition file. I do not have the beta version installed on my machine so have not tried this option

If you have ICEM, you can import CFD "gtm" or "def" file into ICEM and export the same as Fluent "msh" file.

6.3.26 Good idea! It works. Thanks'!

Dear George/Ant,

I have a similar problem, but in the opposite direction: I'am more confortable meshing in Gambit (Fluent) than in Icem. But I need to perform simulations in CFX. So I wandered if I could convert *.mesh files into *.gtm without problems.

Thanks for your answer.

P.S Sorry for my english.

Hi, Laurenjiongo! Direct path. In CFX: File/Import Mesh/File type=FLUENT You can also try following. In ICEM: File/Import Mesh/From Fluent Output tab/Select solver/Output solver=ANSYS CFX Output tab/Write Input In CFX: File/Import Mesh/File type=ICEM CFD

Hi!

I have same problem too, but I've used Workbench Design Modeller. When I was drawwing geometry in Design Modeller, then the article appeared "Import1(beta)". Because of that the mesh didin't work. What can I do?

I would do it in the following way:
Open the CFX solver manager: Tools -> export results - Geometry output only, keep format CGNS.

Then you can import CGNS directly into Fluent, or you can use Tgrid. In Tgrid you can simply import CGNS and just export MSH. Then import MSH to Fluent.

Thank you. But I use Ansys Fluent 17.1 In Ansys, there haven't seen this options.

So, what can I do? I watch this video for removing "beta" options, but it didn't work:

Run CFX solver manager without ansys workbench, not Ansys workbench.
