Hi everyone,

Some questions close to mine were asked here so I'm sorry to, maybe, bother one more time. But can you please give me exact answer?

So.. I tried to connect 2 differently meshed volumes by means of interface. And Fluent created wall regions within the interface (picture attached)... I understand that it comes from different grids at interface zones.

My questions are:

1) Is it the only way to create VERY fine mesh at interface zones? What if I can not afford it?
2) Is it possible to, maybe, change tolerance for the operation to avoid creation of wall?
3) Can I change a type of created boundary zones from walls to, maybe, internal walls or simply delete them (I haven't found such option).
4) I heard that Fluent 14.5 works this out with option "interface matching". Does it help? (I use 14.0).
5) Some other tips and tricks?

Thanks a lot in advance. I'll very appreciate any help.
