fin analysis using fluent6.3
 

Hello friends, im working on vertical fin analysis for natural laminar flow.
so i want to know what boundary condition i suppose to give.
right now im giving three sides ie left right and upper as wall with atmospheric temp. whereas for front side vel in with vel 0.1 m/sec, n for back side press out with back flow 0 and temp atm.
i just wanna knw wether it is right or wrong .
