Tristan Member Tristan Burton Join Date: Mar 2009 Posts: 43 Rep Power: 17	Does CFX automatically use thermal wall functions when you use the k-epsilon turbulence model with scalable wall functions? It's not clear in the documentation if this is automatic or if you have to define the thermal wall functions yourself. When I look at my results files, a wall heat transfer coefficient has been calculated but the wall heat flux is zero! Thanks, Tristan
