Hi Guys,

I am new to Ansys and have probably a very basic question.

I am attempting to run a 2D CFX simulation through workbench. I Have created the geometry and used ansys meshing to do a quick mesh. Now when I try open up CFX-Pre I get an error message "ERROR: In analysis 'Flow Analysis 1': No domains have been defined." and the mesh will not open.

I am confused because I know how to define a domain in CFX pre when the mesh imports however without it importing how am I meant to define domains?

Any help is greatly appreciated.

Thanks

Hello there, I would suggest that after you are done with creating the geometry and the mesh save the project in some directory 'x'. Then when you open CFX-pre just go to file>import>mesh and then import the file from directory 'x'. It should open easily then. Also I would recommend you to start using ICEM for geometry creation and mesh development as its more user friendly and also good for editing your mesh. Thanks

Addendum to what bratzinger said...not only do not use ä,ö,ü in the projectname...BUT do NOT use ANY special Signs in the WHOLE Path!

I had similar problems when I wanted to open a file located in smth. like:

C:/CFX/Projects/Gebäude/Setup/Files/Pre/

and it gave me a similar error just because I had a Folder "Gebäude" containing the folders where my files are stored. I think this is valid also for all other language specific symbols or symbols like %, & and so on....Therefore I now name my files and folders only with standard alphabet and "_" as a separator/space. Because when I use " " (blanks) as space I get problems on unix/linux machines.
