importing ducted fan from catia to star ccm
 

Hi

im new in star ccm. i have some problem with my geometry of ducted fan when im trying to import it to STAR CCM+..i assembled two part designs in CATIA (which is the fan and the others like the flow field and the duct). do you guys reckon that i should do it in one part design or it doesnt matter?

when i tried to import the assembly, only the duct and flow field left in STAR CCM+. also another thing that i tried is to import the fan itself, it says that it cant find the license. is there something wrong with my STAR CCM?

here attached the geometry of the fan and the rest.

thank you
