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 |

Hi,
Just want to know why the gravity was activated in the y direction while the motion is simulated in the x and Z directions. Also, how can we understand the effect of added mass? As you have not included added mass in the frequency calculation. |

Which test cases are you refering to. If the motion is in X and Z and Gravity in y It means it has no effect on the motion. Added mass is the work required to displace the fluid surrounding the cylinder
