rotating sphere boundary conditions
 
I simulated the flow over a sphere. Now I would like to make the sphere rotating like a tennis ball. Is there any predefined boundary condition to simulate this? I would just to impose a constant tangential velocity to the sphere patch and anything would be ok,

thanks,
bye, Francesco

v1.6 gives a new boundary condition named rotatingWallVelocity.

Also you can just create an application which calculates the velocity component for each point if you're on v1.5

Flow over rotating sphere
 
HI how you did rotation to shere by using tangential velocity condition.. please give me hint as i plan to use rotating domain in CFX11 but it uses only fluid domain to be rotating...

Any hint for the same

Sorry,
I abandonend the problem for now even if I am still interseted in imposing rotatingWallVelocity boundary conditions...
sorry for late,
Francesco
