Target velocity for IBM?

[AyushBoral]

How can we modify the target velocity at the immersed body boundary for IBM?

Hi,

ubcx ! Prescribed Velocity in X
ubcy ! Prescribed Velocity in Y
ubcz ! Prescribed Velocity in Z

See https://github.com/xcompact3d/Incompact3d/blob/master/examples/Cylinder/input_DNS300_LR_MOVING.i3d for an example.

Thanks for the reply!!
Actually, I am trying to impose rotation on the 3D cylinder case. Can you suggest the places where I have to modify in order to specify the tangential velocity instead of the default no-slip condition.
Thanks

Hi,
I would suggest to do that with iibm=1 and adapt the velocities in the body subroutine.
