I study in pipe flow by the method of Les form.I set two inlets and one outlet ,and turbulence model set by Les/smagorinsky.I try to mant times set transient form in the time domain,but Starcd always shows mess error. "analysis must be transient and catnot use upwind for velocities to use an LES turbulence model" I already set qick for differencing schemes,but starcd still show the same error message.How to solve the question? thank~

hi ! The message can be ignore if you sure the UVW different option has already changed.

If you want to calcuation LES simulation, the mesh quality is very important. The near wall refine mesh needed.

And the delta T have to be test.
