Questions about operating conditions setting in fluent.

Frank Yang · May 4, 2013, 22:14

The values of physical properties and operating conditions (e.g., gravitational
acceleration) can been adjusted to yield the desired Prandtl, Rayleigh, and Planck
numbers when we model the 'Radiation and Natural Convection'.

How can the gravitational acceleration work?

You know what is the Rayleigh number, do you?

Of course I know, thankyou!

Hi! I am working on a system, in which when i export .mesh file from Gambit to fluent i get following notification. How this can be resolved or What does it mean?

Note: Slitting wall zone 5 into a coupled wall.

Note: Slitting wall zone 6 into a coupled wall.

Note: Slitting wall zone 7 into a coupled wall.

creating bottom_baffle-shadow
creating orifice-shadow
creating upper_baffle-shadow
Done.

If there are no warning or error messages, just overlook them.
But you should check the mesh and boundary conditions in fluent.

i have checked many times the mesh on Gambit, even created new one but same notification, but there are no errors occurring in results...

OK. If you are really care of these information and their means, you shoule make a deep understand of the gambit. That is out of my ability.
