Default Eh what happened to my reynolds stresses

Posts: n/a

I am running LES flow. I reduced my time step on solver to keep cournat number below 1. When I then checked my reynolds stress uu it showed me value of zero through the domain. Flow can not suddenly become laminar, there was turbulence in my model before I reduced the time step. Any idea what is happening here. Any knowledge/guess, please let me know.
