multiphase modelling, boundary conditions
 

Hi all,

I'm very new in CFD and hope you can help me.

I want to modell a simple channel with two phases, water and seeding. At the beginnig of my channel I use an velocity-inlet, at the outlet i use an standard outflow condition. If I make a case-check, there is an error message under the topic boundary conditions, "Change the outlet boundary condition. Outflow boundary condition is not compatible with current multiphase settings."

Do you know which boundary condition I can use for this problem? I'm using the mixture multiphase modell.

Thanks for your answer.
