Angle monitoring
 

Dear all,
I have one deforming mesh problem and would like to monitor the agitador (mixer) angle, so I tried to monitor an expression like " maxVal(Theta)@agitador" which was accepted by CFX-Pre, but yielded an " Illegal argument in call back function MAXIMUM on locale BCP4" error in Post. (similar errors occurred with theta variable or areaAve function)
Note: "agitador" is a "wall type" boundary. How could I monitor this angle ?

Thankfully

The arguments to the call back functions have to be variables. The call back functions are areAve, areaInt, massflowAve ... etc. So, you cannot pass a CEL expression as an argument to a call back function; for example areaAve(sqrt(u^2 + v^2))@Location is not valid since sqrt(u^2 + v^2) is not a variable, it is an expression. You can create an Additional Variable that is equal to the expression that you want to pass in as an argument, then just pass the Additional Variable into the call back function.
