Hello,nWhy do you have a sliding interface in this Fluent simulation? Did you perform share topology on your geometry to make sure you have no mesh interfaces?nAlso, what are your settings under dynamic meshing?nIf you are new to System Coupling and Dynamic Meshing, I'd strongly urge you to go through some of these tutorials from the System Coupling help page.nThank you.nKarthikn
