yes better avoid regions of strong gradients where to place the overset boundary.

Thank you for your reply!

Cubic should be 4th order accurate. So the dissipation is least. Which leads to the strongest vortexes and hence highest lift. Unfortunately I do not have an explanation why the frequency changes.

Hello,
Can you please explain what's the purpose of each transformPoints command in Allrun.pre

runApplication transformPoints -translate '(-10 0.0 0.0)'
mv log.transformPoints log.transformPointsTranslate

runApplication transformPoints -rotate '((0 1 0)(0 0 1))'
mv log.transformPoints log.transformPointsrotate
runApplication transformPoints -scale '(0.0016 1.2 0.0016)'
mv log.transformPoints log.transformPointsscale
runApplication transformPoints -translate '(0 0.06 0.0)'

Thank you
