Trying to get help of the community once more =(
Hi ) i am modeling water displacement from channel with air using Turbulent two phase flow, Level set.
First, i try to simulate simple model and everything worked well (laminar problem), but when i try to make it turbulent it failed,
"Failed to find consistent initial values" or problems with convergence,
I read all help documentation searching for some solutions and try different things, but - nothing =(
i understand that my problem is - i cant correctly model turbulent flow of air in channel (boundary conditions and initial values) and i don't know what to do. Every time i get this two mistakes!!! =(
i see @turbulent backstep@ in model gallery, but it is rather strange example.
May be there is another simple example of turbulent flow in pipe? or what can i do? I checked boundary conditions and initial conditions many times, used help, tried different things with mesh and stabilization....
attached file - for laminar problem, if someone can make it turbulent or advice me something, God bless him
