Unhappy Turbulent problems during Dynamic Mesh Motion

Hi Everybody

I am working a case using Dynamic Mesh (Layering, Remeshing and DEFINE_CG_MOTION). During the running (mesh motion) and from the beginning, this message appears continually.

“reversed flow in 40 faces on pressure-inlet 9.
turbulent viscosity limited to viscosity ratio of 1.000000e+005 in 42 cells”

So, it generates absurd pressures on the rigid body.

Please, I need some help.

Arturo

hi there

in my opinion this message is common at the beginning of the iteration

if the message keeps going I suggest that the model should be checked

Hi There

That message appears along the iterations.

Please, what should part of the model be checked?

Regards
