temperature normal gradient on a boundary

Sandrine · June 10, 2009, 13:26

Hi,

I impose temperature on my wall.
After convergence, I would like to post process my results :

I would like to get normal temperature gradient on a boundary and on a surface (plane created in fluent with surface => plane tools)

C_T_G macro is not adapted because it gives celle temperature gradient and my surface is constituted by facets
but F_T_G doesn't exist.
How can I manage to get the temperature normal gradient ?

I shall be very grateful if you would take a little time to look at it...

Best regards, Sandrine.

The way I have done this is by making a plane, as you have, and then exporting the temperatures of the plane. I can then look at them in Excel of whatever I chose. You should be able to view your plane to make sure it is where you want it.

I am looking for the solution of NSE of a flow over a flat plate using Lattice Boltzmann Method if anyone have something related
