Hello,

 

You can use CEL (CFX Expression Language) to define fluid property variation through an expression if it is required. For example, you could define Dynamic Viscosity to be a function of Temperature.

Chapter 31: Expressions (ansys.com)

If you are not able to access the link, refer to this forum discussion: How to access the ANSYS Online Help

 

Thanks!
