Dear All

I have some problem with the correct format of nonuniform List<vector> for my inlet boundary conditions for U in 0 Folder.
I want to specify a nonuniform velocity for U at inlet for my LES calculation from my previous RANS calculations output.
In nonuniform List<vector> we must specify only the U in the inlet faces like this:

Code:
value nonuniform List<vector>
32

What I found is that 32 is the number of faces in inlet (not the points) and there is no need to specify the coordinates of the faces but what I don't know is the arrangement of these data in x,y,z directions??what is the coordinates of the related faces and where are these defined so that OF can detect them correctly?
so here is my question:
how can I export my inlet from my previous RANS calculations at the inlet patch to have the above format (i.e. the values of velocities at inlet faces with the OpenFOAM Format) without the need for arranging them manually. since my inlet have more than 4000 faces so it is impossible to do it manually.
I have used the sampling utility in inlet for my previous calculations but it gave me the values of velocities at points not cells.
Does anybody know how can i do that?
Thanks for your helps in advance.
