UDF for oscillating airfoil
 
Hi,

I need an urgent help, i need a udf to be able to make my airfoil oscillate. am using fluent.

Hi,

Why not have a look on the Fluent's UDF archive? Check the 6DOF UDF. You can take your problem further from there.

Good Luck, Amr

Re: UDF for oscillating airfoil
 
1) I have two zones in my grid.first zone near the wing is structure and the other is unstructure. if I use moving grid and udf, can i oscillate the structure zone during remeshing unstructure zone and stucture is fixed.

2)I defined a geometry that i splited the mesh of it into 2parts(structure & unstruc.). the near zone to wing is structure and the other one is unstructure.Between two zones, i defined interfaces.in fluent after defining B.C.,interfaces,...,check geometry i doesn't have any problem, but after intializing to start solution, Fluent shows me Warning and when i check the mesh, it fails and i'll have handedness problem(right-handedness & left-handedness)
