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.

Sorry, I can not help you with Gambit.

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

Good luck,
Tom
