If you are using the ANSYS CFX Export Utility to export your results for use in another post-processor, by default, the boundary-node corrected values are used, if you are using the ANSYS CFX-Solver Manager. You can choose to export the original, uncorrected values by toggling Use Surface Data on Boundary Nodes off on the ANSYS CFX-Solver Manager Export form. If you are running ANSYS CFX Export from the command line, then the default is to use the uncorrected values unless you specify the command line option -c.
