Default UDF for calculation UDS flux on wall (specified value"0" for scalar)

ananth_01 is on a distinguished road
I am looking at settling of small particles (5-150nm) in monolith channels using both UDS as well as DPM approaches. The results are consistent for laminar flow using default FLUENT models for drag and Brownian motion.

The issues with DPM for turbulent flows has been widely reported in literature. Hence I am planing to work with UDS. However I am only able to get the overall particle deposition efficiency using UDS by specifying UDS fraction on wall to be zero.
1. I want to plot UDS concentration on the wall. how should I store the UDS concentration on the wall?

2. Can I move the wall depending on amount of particles settles during transient UDS simulations?
