EWF DPM coupling

I am using a UDF to trap/stick DPM particles when they hit the wall. After that, I want to use the trapped particle mass and momentum as source terms for the Eulerian Wall Film model.
If I provide the wall-film momentum source using a UDF, should I consider particle and film velocity in udf to get momentum source? if yes, how can I access the Eulerian Wall Film velocity inside a UDF? Is there a specific macro for film velocity on a wall face? or how can i calculate it?
Since the wall film flows parallel to the wall surface, should I use only the tangential component of particle velocity in the momentum source, instead of the full particle velocity?
