Hi,

I've got a simple problem in CFX Pre 15.0 but can't handle it.

I want to create some Expressions to monitor some Variables during the Solver Run. Therefor i want to make an expression that counts ("countTrue") the number of nodes in the grid that have bigger Residuals than an specific value for every Timestept (or Loop). During the Solver Run i want to plot this expression and observe the convergence.

I already know how to do the Syntax and all the stuff. But I can't find the Residuals (U Mom, V Mom, P Mass...) as Variables in the area where you usually create the expression.

Isn't it possible to use the Residuals like usual variables ?

That's only to record the Residuals for the Solver or CFX Post. But i want to use them as an variable to create a new Expression, already in CFX Pre.

Residuals are not available via CEL.
