Hi All does anyone have any guideline to set the turbulent engery (TKEI) in the initial tab?

I think it depends on what you are trying to represent in your simulation. Is it about a virtual wind/water-tunnel? Or a GMO moving in quiescent fluid? Or what else?

Stefano it is case where GMO is moving from x+ to x- while impinge by water jet. so do you have any idea on how to set the TKEI? or do you have general guideline to set this parameter?

I think that if you want to represent an object moving in quiescent/calm water, than probably the best realistic condition is to set tkei=0 (you don't have turbulence in a water that is not moving). Instead if you are representing an object invested by a fluid flow, like in a wind-tunnel, then you should set the turbulence equal to the one of the wind-tunnel (sometimes known) or leave it to the default value that is a small number, but not zero. Tell me if this helps...
