Hello, 


You will need to do meshing in Workbench meshing. 


In Workbench, you can do geometry operations using Design Modeler or SpaceClaim. Then once geometry is ready, you can do meshing in WB Meshing. Then you can take this mesh to Fluent. 


You can do meshing in Fluent when you start Fluent in Meshing Mode. Here you can import stl or any cad file. But it would be a faceted data. Then you can do surface meshing of wrapper. For more information, please see help. 


Regards,


Keyur
