Hi,

Does any one knows wether it is possible to aaply logarthmic wall functions in Comsol on two walls simultaneously in a model. I mean lets us consider two concentric cylinders and let us assume that the inside cylinder is a solid rod with some internal heat generation and within the annulus some liquid flows, then in this case can we apply the logarthmic wall functions on the inside solid-fluid interface and as well at the external wall. what boundary conditions shall we use if the flow remains laminar?

Thanks in advance
