Hi,

I have a finished run, and I want to calculate the Nusselt Number in each cell on a plane. I have all the variables that i need, but i don't know how to tell the post through an expresion to calculate the variable in all cells. my mess is only hexas with inflations on the walls (i don't know if this matters)

any idea

thank you

Create an expression that calculates Nu. Then create a user variable that references that expression. You'll be able to post process your newly created expression variable then.
