Hi everybody.
I would like to model a micro-channel under slip boundary condition, but I don't have any tutorials or videos, moreover I don't know how to check its accuracy.
I appreciate it if you could help me.
thanks in advance.

The slip condition in microchannels is not always valid. You have to determine if it is valid for your case or not. And there is hardly ever a full slip in a microchannel. For full slip, you can use free-slip condition available; specify shear stress of 0 at the wall. For partial slip, you have to use expression or UDF and you need to decide whether you want first-order or second-order slip model.
