Hi,

May I ask how to separate the mesh of one zone based on the geometry of another zone?

Let's say

big zone is zone A (the whole domain includes the small one),
small zone is zone B.

Say I have generated the mesh of whole domain A and zone B respectively.
Then I import the mesh A and mesh B to fluent, I would like to separate zone A by boundary of domain B.

May I ask does anyone know how to make it?

Thanks in advance.
