(in CFX-5.x) thx bogesz

 February 4, 2004, 05:03 Re: monitor the location of MAX value #3 bogesz Guest   Posts: n/a 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.

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
