Find the value of the coordinate "z" when a variable exceeds a given value in Post
 
Hello dears,
I'm in Post processor.
I have a cylindrical part with z axis as symmetry axis.
The variable viscosity grows along the axis and I want the value of the coordinate z when the variable exceed a given value (fixed by me). How I can do?
Thanks!

Use an expression (either mathematical or an interpolation function) which describes the viscosity as a function of anything you like and set the fluid viscosity to that function.

Thanks, I resolved using an isoclip until the given value of the variable, and then giving a point at a boundary of the isoclip. From the calculator post, with the probe I can see the coordinate z of the point that I want.
