Ansys CFX Post: Evaluate Nusselt Number with Expressions

Towe91 · March 6, 2017, 15:00

Hey guys!

I have read a lot of threads the last days about how to calculate the Nusselt Numbers with Expressions and Variables, but it doesnt work for me...

It doesnt matter which expression I am typing in I always get the same Error (see Picture 1).

I would be so thankful any help I could get!

Your don't put the "Nusselt Number = " bit in the window. Just put the equation.

Alternately you can just fire up the CCL editor and then you will have the
"Nusselt Number = XYZ" syntax you are familiar with.
