Bit difficult here to help as you can have situations where on both sides you have different cell id's and for that reason one should start searching for the associations or better cell partners. This can be done via F_CENTROID and some tolerances. After that is fuillfied you can save the cell id and thread id in cell memories. Afterwards it is easy to loop over the faces of one side, access the cell id and thread id of the partner (on the other side) and do what one wants to do. This is how one would implement a membrane!n
