Hi all,

I read some reference book that says "you must set up mesh interface in fluent panel in order to make sure two computation domains between a interface can exchange data, in other words, fluid can go freely through interface"

I also know interior boundary condition can also guarantee that data can exchange between two computation domain.

Then what's the point of setting up interface boundary condition? what is the difference of interface and interior boundary condition?

Best regards

Weiqiang

do you mean interior type does not guarantee data exchange?
