The coordinates of all grids in the inlet boundary

Hello，everyone!

How to obtain the coordinates of all grids in the inlet boundary??

#2

You have defined the inlet, so presumably you already know the coordinates of the boundary. Can you provide a little more detail about what you are trying to do?

Hi, cgw !

Thank you for your reply. I want to implement a shear flow field at the west boundary of the inlet, and the value of the shear flow field is related to the coordinate of y.

#4

Is this the same question as Shear airflow field at the entrance ?
Please provide more details about what you are trying to do. Are you writing a UDF for the inlet? Can you share what you have done so far?

hi cgw， thank you reply!

I haven’t written a UDF yet.
My current idea is as follows:
for example, there is an velocity inlet on the west side in the x direction. I want to define the x inlet velocity on the west surface based on the y-coordinate of each inlet grid.
I would like to confirm if it is possible to achieve this by loading UDF？？
thank u
