Default LES - periodic PLEASE HELP!!!
Posts: n/a
Hi, I'm trying to LES a sector (say 30deg) of an annulus. The flow is in X-direction. Is it OK to define periodic BC on the two faces inclined to each other by 30deg (i.e. those parallel to X-axis)? Should a special care be taken due to the fact that these faces are rotationally periodic? If yes, then how I should do it? Can it be done in Fluent without modifying the mesh? Should I check the "reversed" box in Gambit while linking the two faces in question? Thanks a lot.

Fluent should be able to do it without modification (assuming its LES mode does work!). And yes you have to click reversed box in Gambit. Since version 2.0, the reverse button is set as default by Fluent Inc.
