The Boundary condition i specified has changed after computation
 
I'm simulating a Heat exchanger in fluent, i specified boundary condition: mass flow inlet to a fluid with temperature 633K. After iterations the result shows inlet condition to be 603K.

I am using Standard k-epsilon model

Hi,
are you sure your boundary conditions -> reference values are also set to your inlet conditions?

Nemish March 31, 2016 07:20
How do i do that?

Where do i check if the reference values are set that way

workbench -> setup -> setup -> reference values

Is there some way it could be done in fluent, i found the reference value in reports, I have two mass flow rate boundary conditions. But there only one can be mentioned. What to do for 2 BCond

Maybe this tutorial can help you?
