Forced convection in acusolve,

Hi friends,

i want to do forced convection problem in acusolve. but i know only natural convection(i.e assigning body forces). please, can anyone send me the how to setup the forced convection parameters in acusolve. 

problem: thermal analysis i.e external (wind tunnel) flow around the solid rectangular object. for prediction of heat transfer coefficient.this h value do not depends on inlet flow temparature , it should be depends on inlet flow velocity(by forced convection) .

so, please can anyone suggest me with solution. i  am waiting for your solution

..thank you
