If i need to creat a new user field , i have to invoke a wall y+. Is the value of wall y+ i invoked cell value or face value?
I need to creat a new wall function by user field function to change every cell parameter. I don't know whether i can access my goal. Whether is the user field function not enougn and have to use user code?
Appreciates！
I think user function can handle this, and you will be using the Y+ of the cell
According to the user guide "Field functions provide a mechanism by which fields (scalar or vector data that are evaluated at cells, vertices, or boundary faces) can be viewed and defined in STAR-CCM+."
So, I think that wall y+ is evaluated on the boundary faces.
Using 'Field functions' you can get all the stored field data, both at cell centers and boundary faces. If you are only interested in Cell center values, then activate the option in user function , 'Ignore Boundary Values'. Hope it helps
Could you say me how get the local mass flow in cell and boudary area face?. I want them to use in a user function.
Thank all of you for your help
Dear Satish Bonthu,
Could you indicate how? or introduce a ref.
