Default Boundary conditions in channel flow with wall model

GCMS_A is on a distinguished road
Hi all,

I would like to simulate a channel flow with dynamic wall model. To be able to do that, I need some help from the Foamer's community.

First, I need to modify the boundary conditions files (see the BC.tar.gz file).

In my opinion, I must modify the lower and uper Boundary conditions in the three files.

In the U file, i would like to replace the velocityABLWallFunction type ( specially designed for the atmospheric boundary layer ) by another one but I don't know what can I put that in place. Furthermore, I would like to replace the Slip type by the same first boundary condition to represent a channel flow not an atmospheric boundary layer.

For the other files, I have no idea.

Can anyone help me ?

Thank you
