Expressions using input parameters
 

Hello forum,

I am new to Fluent, having used CFX previously. I am working on a non-dimensionalised problem. As an example, the thermal conductivity of the fluid is 1/sqrt(Ra), where the Rayleigh number is input externally, directly from the project schematic. How can I specify the thermal conductivity as that expression in the setup?

I will be conducting a large number of simulations, so I would like not to have to calculate these myself and change everything manually every time.

Thanks
