Zero is correct. However in certain circumstances it may be interesting to get "pseudo" velocities at walls - eg. to calculate surface streamlines or make contour plots of velocity magnitude "directly at" the wall. Therefore I want to interpolate some velocity values to the wall as other postprocessors can do. > > On Tue, Jul 7, 2009 at 2:50 PM, bastil2...@yahoo.de > <mailto:bastil2...@yahoo.de> <bastil2...@yahoo.de > <mailto:bastil2...@yahoo.de>> wrote: > > Hi all, > > I do an export from my CFD code using node-values.
