any suggestion about method to use?
 

Hi:

I am using fluent and trying to model following case:

in a tank (close to a cube) which full of liquid (water), a sheet (solid) is moving up and down (oscillation) in the liquid (the sheet always stays in the liquid). the dimension of the sheet is slightly small than that of the tank, so the presence of tank wall may not be ignored. i am interested the flow near the plate, especially the shear stress. any suggestion how to model this case?


many thanks
