RSM mesh requirement

Hello,
I would like somebody to confirm I understood well what I've read so far. As I understand it, the SSG Reynolds stress model uses wall functions to solve the boundary layer. The Y+ values can there for be quite large, say 30-100. On the otherside, the BSL Reynolds stress solves down to the wall and so the Y+ should be kept below 2, as far as it is possible. The latter model should therefore be more accurate on the amount of separation predicted. Is there anything else I should know concerning mesh requirement for the RSM models ? I usually use 2-eq models. Thanks a lot, Felix |
