[Commercial meshers] Mesh an oscillating airfoil with gurney flap

milad092 · August 22, 2018, 13:33

hi everyone
i want to mesh an oscillating airfoil with openFOAM. the problem is my airfoil mesh. i cant run this case in wing motion because of the mesh!!
i want to ask if any body have any experience in simulating airfoil with gurney flap in openFOAM?
i want to mesh this airfoil in gambit .
thanks

Hi,

You may want to consider using overset mesh technology if you have quality issues with the mesh. Or, if you are just oscillating around a point you can use an AMI interface between the rotating and stagnant part of the mesh. Than you have the same quality off the cells during the simulation.

hi tom
in fact i want to know procedure of dynamic mesh airfoil.
i do not have enough information about dynamic mesh in gambit. i attached 2 pictures that explain my case.
i hope you can help me
thanks
the first one is my case
the second one is the complete mesh of my case

Sorry, I can not help you with Gambit.

For OpenFOAM, maybe you can have a look at these tutorials.

Good luck,
Tom
