Hello my friend.
I simulate one long pipe that fluid ( Gas - Methane) flow in.boundary condition are :
inlet: velocity inlet constant velocity 6.85 m/s
constant heat flux at ambient of pipe that is 23100 w/m2
the reference that i use for validation used the outflow boundary condition for outlet. But when i apply this boundary condition (Outflow) the software make warning that 'Maximum Temp. ex. at ****(some digit.) face'.
be mentioned that flow is fully developed at exit.
please help me

Hi
You can ignore this warning by increasing solution limit of temperature in the following address:

Good luck
