there are too many zones when i decomposed the geometry and meshed the volume by different method.
something likes this, i have decomposed the brick by plane,merge and imprint it,and meshed two wolumes with tet method and sweep method,like the picture.

i found there was two fluid zone when import the mesh to fluent, that is not i want. i just want one domain,and the cut plane become interior type. how can i do?
