how to set inlet and outlet inside a hard disk drive?
my case if to investigate the fluid flow inside the driver.

What does your domain look like?

What are the pressure/velocities at the inlet and exit? Set the pressure/velocity bc's to those.

Well, for my case is to investigate the fluid flow inside a hard disk drive.
To determine the characteristic of air inside the drive in term of velocity and pressure..
now im facing 2 problems.
1st: my maximum skewness has exceed 0.9, which is having a poor quality of meshing element.
2: according to survey journal, I found out that the author take the spinning disk as inlet.

so,how to improve the quality of meshing
and how to set the disk as a rotating inlet?
