nutUblended wall function gives rise to pressure spikes for a periodically pitching airfoil
For a periodically pitching airfoil the nutUBlended wall functions gives rise to pressure spikes. The reason is the line
const scalar uTauLog = kappa_*magUp[facei]/log(E_*yPlus);
I changed it to
const scalar uTauLog = kappa_*magUp[facei]/log(max(E_*yPlus,1+1.0e-04));
and the pressure spikes disappeared.wingMotion2D.tar.gz
Steps to reproduce
I added a small example case. Python script to plot Cp, Cd and Cm is included

What is the current bug behaviour?
What is the expected correct behavior?
