Velocity slip+temperature jump B.C.
 
Does anybody have any UDF for velocity slip and temperature jump boundry conditions in a micro-channel?
I am not familiar with C programming,and UDFs that much.
please help.

I have the same question! )

What kind of problem do you solve?

As far as I understood, these BC have been already implemented for pressure-based problem. But I don't know how to use it for density-based problem.

I found theory formulation in theory guide:
7.2.3. Slip Boundary Formulation for Low-Pressure Gas Systems

But I can't find example how to use these BC even for pressure-based problem.
