I can't resolve user function problem

Hi everyone , I have a problem that I can't get CFX realizable of User function.

user functions is defined 1D interpolation coordinate units is [m],and value units is [m/s]. and I use user function from Expressions like userfunction(r)
and calculate it ,but when i refer to Expressions in CFD POST, error message appear,"the following unrecognized names were referenced,userfunction,r"

can anyone help me , please?

User functions are only available in CFX-Pre and CFX-Solver.

Unfortunately, they are not currently supported in CFD-Post.

So, you mean I can't get value of user function in CFD POST ?

I'm not sure whether the value of user function is correct.

You can create an algebraic additional variable equal to the function, and post-process such variable

Additional Variable = userfunction(r)
