Interface duplication in Fluent

StormedStar · March 7, 2016, 22:11

Dear All,

When I draw my geometry, consisting in 2 phases (air and water droplet) as I attached, I see later in Fluent that it creates two times the interphase between liquid-air (droplet surface).

The two interface are the same but they have different names, contact region 2 src and contact region 2 trg. The problem is that I have a lot of pressure increase across the interface with little time, so I think that this can cause it, so how can I delete one of them?

Thanks for all

Do you have them as separate zones or a single zone?
If separate zones there should be two surfaces to the interface (a source and a target). Even if not, most interfaces come in pairs (always a source and target), otherwise there is no interface.

So is it normal then?
