Rayleigh numbers??
 

Hi all,

Is there a way to get Ra plot in fluent?

I have only managed to get Nu # plot.

Pls help. Thanks.

Fluent has no possibility to plot Ra number directly. But you can esily do that. Use Custom Field Functions do define the Rayleigh number as a custom field sclar.

Hi Michael,

Thks for reply.

Can you explain it in more details? Where is the custom field functions? How can i define Ra as a custom field scalar.

I'm new in using fluent, hope you won't mind.

Thks.

Go to define-> Custom field functions. There you can specify your function. After definition you can display contours of your defined function on selected surface. Good luck.
