[Nek5000-users] Calculating wall shear stress and dimensionless wall distances

[nek5000-users at lists.mcs.anl.gov]

Hello,

Background : I am trying to perform a LES in a turbine blade where the
stream-wise, pitch-wise and span-wise direction is along X,Y and Z axis.

Question : I would like to calculate the yplus and zplus values for the
nodes close to the blade. For calculating the dimensionless wall distances,
one would require the velocity gradients in the respective direction or the
wall shear stress . I would like to know if there are any subroutines
available in nek that would help calculate the wall normal distances or the
velocity gradients ?

Any help is greatly appreciated. Thanks

Regards
Shriram Jagannathan
