is it possible to monitor the location and the value of the maximum value of a given quantity? for example during a trans. where and what is the Max temp and how's the location of it moving?

(in CFX-5.x)

thx bogesz

As far as i know there is no dynamic post processing in CFX-5.But definitely you can create a monitor point in PRE and view the value of the parameter while solving. shashwat

Thanks, I already knew that, but in Pre it's only possible to give the coordinates of the desired mon. points. I want to define them as the locations of the MAX of a given variable. (or the location of a given value) Is that possible? Is there an expression to define that?

Of course I can have this data via postprocessing. But that's the meaning of the monitor point - monitoring values during the process of the calculation. Please let me know if I was wrong.

Hmmm....

For a tabular output, it should be possible to create a CEL function like:

Find_max(Value,x,y,z) REAL MaxVal,SaveX,SaveY,SaveZ SAVE MaxVal Loop over all elements

if (value > MaxVal)

MaxVal=Value

SaveX = x

SaveY = y

SaveZ = z

endif end loop write(70,*) MaxVal,X,Y,Z end

(using the appropriate FORTRAN syntax of course)

If you want to see where this is graphically on each time step, set an algebraic AV to 1.0 at the maximum, and zero everywhere else. A transient animation of an isosurface of this AV at 1.0 will allow you to watch it move around the domain.

Good luck. Jeff
