Default Reporting volume averaged temperature

Dear all,

I am doing a transient simulation of a room, including the construction materials of the walls in ANSYS FLUENT 14.0. I would like to have the volume averaged temperature of the room for every time step. I looked at the calculation activities however in the "Quantities" list I can only find "Static Temperature" and "Total temperature" and when I choose one of those two options I get a file with the values of every cell in the room.

Although I can easily add the values and divide by the number of cells, is there a way to get only one value (that of the volume averaged temperature) instead?

Thank you very much

Dimitris

I think what you want is under the "Reports" section. If you choose "Volume Integrals" you should see different Report Types like Mass-Average, Minimum, Maximum... for different field variables that you can calculate for specific cell zones. Clicking "Compute" will show the calculation in the terminal window.

Thanks for your answer NormalVector,

I know that after a simulation is over you can check the volume averaged values in "reports". However what I am looking for is a way to obtain the volume averaged values of a cell zone for every time step of a transient simulation, preferably exported in a file.

Ah okay, I guess I missed that in your post, sorry. Have you tried creating a volume monitor? You can export that every time step (I believe) and it looks like you can get what you want, Volume-Averaged Static temperature.

Dear NormalVector,

Thank you very much for your help. Indeed there is an option to write the quantity from the volume monitor to a file, for each time step of the simulation.

Thanks a lot!
