Defining UDS at interface, Boundary Zone Walls Sliding Mesh
 
Hi,
I'm running a Rushton Turbine simulation, and created 2 extra transport equations using UDS. Using MRF I have good results but as soon as I switch to SM, my UDS values at the interface are reduced significantly. I think is because when Fluent creates the interface, it also creates extra Boundary Zones, in my case are Walls. At these walls the UDS values needs to be specified. At the moment I've left them with Specified Flux=0 as I did with MRF condition. But it seems that this condition is affecting the information transfered through the interface.
Any Ideas on how to overcome this issue?
Cheers,
Javier
