Hello everyone.

I am new to using ANSYS CFX and am currently working on a simulation model on ANSYS CFX. It consists of a dome structure which is experiencing wind velocity due to atmospheric turbulence.
So, due to the wind velocity, there would be minor fluctuations in the refractive index over the dome.

I wish to add refractive index as a variable or an expression using which I can know the changes in 'n' because of the wind velocity.

Thanks in advance for comments and advice.

PS While trying to set up an expression for the same, I did find refractive index as an option under

Definition---> Variable---> Reference Pressure---> Rotation Velocity Z---> Refractive Index

but I don't know if I can use it or how.
