[FAQ]

The maxVal, minVal functions won’t return nodal data. Value ranges reported by the function calculator may differ from the values shown by a contour. The function calculator results are based on cell/face values while contours show values based on either cell/face values or node values; for details, see Variable Location: Vertex and Face Options. However the max/min values can be retrieved with a Perl script that can run in CFD-Post. Please write a Perl script which would do the following:
1. Create a contour of nodal data on the desired surface for a given variable.
2. The data for the contour will be exported to a .csv file.
3. The script would parse the .csv file for the min and max values.
4. Expressions would be created and set equal to the retrieved min and max values.
