time step in transient flow

Sorry¡Amaybe I didn't describe my problem obviously in last message¡CMy question is --> if I consider a transient problem by CFX4.4 ¡Aa cube was to be build¡Aand set a heat flux on surface(just only one surface)¡Atime step is (10*1)sec¡C

After that ¡AI saw the temperature distribution wasn't to be conducted¡Aeven if I try larger heat flux¡AI got the same temperature distribution in the same region¡Ajust only the temperature scale was different¡Aand the lowest temperature was the same ¡C

In fact¡Aif we set a large heat flux value¡Adue to have a large energy ¡Athe temperature should be conducted to all cube immediately¡Abut why it was so slowly of the temperature¡Acan anybody do me a favor to solve this problem?? thanks in advance!!
