Hi, In CFX-Post, I want to plot contour of 'Turbulence Kinetic Energy / Turbulence Eddy Dissispiation'? How to do it? I think I need to create an expression but I am not able to do it correctly. Please some body guide me. Thanks a lot, Kushagra

You need to create a Variable, not an expression (although your variable can be set equal to your expression).

Create a new variable and set it equal to your expression as you had it:

Turbulence Kinetic Energy / Turbulence Eddy Dissispiation

It's hard to believe, but you can just write equations where you need them. That's the power of CEL!

The reason expressions in the expression editor don't appear as plot variables is because variables need to be calculated and stored in memory. If Post did this for every expression it would be too expensive (and not generally needed). If you have an expression in the expression editor which you are interested in plotting, just add a variable and pick your expression in its definition.
