Inlet boundary condition

I am doing 2-D flow cavity noise calculation with the inflow boundary of the domain attached to the no-slip boundary of the cavity. ->| ->|___ _________


I therefore need to specify the boundary layer thickness at the inflow boundary by because the velocity is zero on the wall. Can anyone tell me if this can be done or how to specify the boundary layer thickness of inflow boundary in fluent ? or should I let the boundary layer develop, but this method doesn't give much control to the BL thickness

Thank you very much,

Re: Inlet boundary condition
you can do this using a DEFINE_PROFILE UDF
