I have some questions about the new functionality Monitor Statistics in CFX 16.0.
With a CEL expression it is possible to access Monitor Values (here I use the arithmetic average of an expression) :
probe(Expression Value.Arithmetic Average)@example
Letís assume that example uses a Moving Interval defined on 40 iterations.

When I try to use probe(Expression Value.Arithmetic Average)@example in CEL I have this error message :
================================================== ====================

| ERROR #001100279 has occurred in subroutine ErrAction. |
| Message: |
| Stopped in routine CEL_WRAP |
I think itís because the moving interval needs 40 iterations to do the arithmetic average. At the Iteration 1 it is not defined. But, even if I write in CEL something like :
If( Accumulated Time Step < 40, 1 , probe(Expression Value.Arithmetic Average)@example)
I have still the same problem. Do you have a solution ?

I have found the solution I post it if others have the same problem in the future.

My problem was that my inlet boundary condition depends on the expression probe(Expression Value.Arithmetic Average)@example (defined with a moving interval of 30 iterations). Consequently, the 30 first iterations, CFX can't do the calculation because the value of the expression doesn't exist. The solution is to make an artificial run just to initialize the second calculation.

Good bye
