Hi,

i am using Ansys12-fluent

i am working on rotation of cylindrical can.

when i give rotation with moving mesh in cell zone condition and set rpm and same follow in boundary condition, then whole can moves in a long circular path instead of rotating at its own axis.

x=1 y=0 z=0 and x=0 y=0 z=1, where z is height.

and
when i will put x=0 y=0 z=0 and x=0 y=0 z=1 can will rotate on its own axis but at the center of can velocity remains 0.

what should i give so i will get axial rotation of can and at center fluid have some velocity.

If i give only wall motion and not cell zone motion, is it correct?

what is difference between moving mesh and moving reference frame?

though in fluent tutorial guide they advised to use moving reference frame for rotation but in animation u will get actual can rotation with moving mesh instead of moving reference frame.
