Sorry for the confusion. Gravity is in the correct direction. the axis of symmetry being x this time and z that time was due to importing issues(in another question here). Once the importing made the...

maybe just another remark: when I let it run from standard initialization with standard completion residual=1e-3 then everything looks symmetric without backflow. its just when I decrease the error...

So to give you an example of what it looks like. Atm in this picture I used the outlet at the bottom as a pressure outlet and the top inlet...

Gravity is alligned along the -x axis.
When importing my model in the design modeller it somehow chose the axis of symmetry to be the x-axis :-/
But it shouldnt matter as long as I have the correct...

I uploaded the outlet where I have backflow. The hole in the middle is not due to "clip to range" but actually the flow cant go there...

I dont know what u mean by the backflow species is ignored?
The specified massflow and the mass fraction in the species tab at the boundary conditions do not refer to backflow, or?

That's what...

So how are boundary conditions treated during calculation?
Are they forced at each iteration or what impact do they have on the calculation? Coz the set boundary conditions do not necessarily mean...

Boundary Conditions

When Specifying the boundary conditions in Fluent when working with species one has to give a value for the mass fraction through that inlet or outlet.
Now I'm wondering whether this value is really...
