Dear friends,

I am trying to create boundary layer structured mesh in ICEM. I would like to define specific number of boundary layers.

What I understood is that in Pre-Mesh Params > Meshing Parameters, Spacings just determine the height of the first/last cell and using Ratio the height of the adjucent cells of them are determined. But in this part we are not able to define the number of boundary layers.

For the rectangular shape below, how can I define a certain number of boundary layers on the upper wall ?

Thanks in advance for any help.
