UDF for heat transfer coefficient
 

i am studying on natural convection over plate(vertical,horizontal or inclined),i wonder that can i change the surface heat transfer coefficient with udf ? if i can then which macro i should use (DEFINE_ADJUST,DEFINE_HEAT_FLUX,DEFINE_EXECUTE_END or DEFINE_PROFILE ) ?:confused:

We once used DEFINE_PROFILE to update the heat transfer coefficient. The HTC updated as surrounding temperature. DEFINE_ADJUST should also work fine.
