Pitching Airfoil in FLUENT

I want to simulate a pitching airfoil in fluent. I have 3 zones, freestream, outlet and walls (airfoil). There are also fluid and default interior is appearing the zone options.

1) I have used the UDF that is also posted in this forum

2) I compiled the UDF sucessfully

3) I have to choose the dynamic mesh

I go to Define-Dynamic Mesh-Zones

At this point, I need urgent help.

I choose airfoil (wall) as Type - rigid body
Motion /UDF--UDF I have compiled

I don't know if this is enough? Should I choose fluid,default interior, free stream and outlet zones as Type-Stationary?

Any help,
Thanks a lot,

Hi Salih,
Sorry i cant help you in this regard, but i need help from you. Could you please post the UDF.

Hi Salih,

I don't know if I am using the right approach, but on the airfoil I usually apply the rigid body with boundary layer, you can go to the meshing options and set a Cell Height that can deform along your wall zone, as an adjacent boundary layer.
I also create a dynamic mesh zone on fluid and int_fluid as deforming, and then you can set the zone parameters to maintain quality.

Hope this can help you.

Best regards,
