ERROR: ...No Domains have been defined

svanmunster · January 31, 2012, 21:29

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
