Hello,

I have to make simple analise of plate 1x1: top and bottom wall adiabatic, left - cooled and right heated for Ra number = 10^6. And I have 2 questions:

1. Where in fluent I can declarate Ra number? Can I do it directly ?
2. I understand that adiabatic means heat flux =0 so cooling mean heat flux with minus sign and heating with plus sign ??

I will appreciate if someone could simply explain me how to do this.

P.S I was looking other topic on forum but I couldn't have found answer.
