Default Partial slip wall BC

Posts: n/a
I am working on simulation of fluidized bed. I need set the partial slip boundary condition for the solid phase on the wall. If I write the UDF to do this, where should I hook the UDF? The 'Specified Shear'? By the way, What's the difference between the specularity coefficient and specified shear? Sorry for such simple questions, thanks in advance.
