i am working on my master's degree thesis and i am trying to do flow simulation through a pipe of an heat exchanger, but i can not seem to put the right settings to get the right results and i have to wait 12h to try again.. the problem is i can't simulate heat transfer from liquid running through the pipe with the pipe together with heat convection to the air around.. i am using 3dexperience platform.. do you have any advice or where could i look for examples?
