How to import CAD file into ANSYS Fluent?
Fluent imports IGES, NASTRAN, STEP, Pro/E files as far as i remember. Try gambit for modeling in Fluent.
Export the file into IGES format. File Save as Change the file type to “IGES (*.igs)” Click “Options” Change the “Surface representation/System preference" from "Standard" to "ANSYS" Click "ok"..
Here i attach an file that i got on the web.

This for CAD files from SolidWorks to ANSYS
I will offer other option, instead of Gambit. My suggestion is to used ANSYS Workbench or more better option Icem CFD which represent from my point of view the best tool for mesh dedicated to CFD study (in most special).
Keep in touch.
