Please help me!!!!!!! analysis of a semi salvage rotating cylinder in a fluid
 

hi everybody

Can I analyze a semi salvage rotating cylinder that placed in a fluid by Fluent?!?!?
the half of cylinder is in water and the other half is in air and cylinder is rotating with a constant angular velocity.

Is it true that I must use multiphase and dynamic meshes?

Please help me.

I think you can use multiphase model and assign an angular velocity to the wall of the cylinder.
I think there's no need for dynamic mesh.

Thank you Daniele,

But I need the shape of water while the cylinder is rotating, does Fluent give me it without using dynamic mesh? actually I have two fluid zone: water and the air above it. do i need to consider the air above the water?

again thank you
