Hello all,

My mesh is a large domain with two tubes inside it, and they are different domains. So I want to use multizone to simulate the outer large domain, and I selected the face without two tubes as the source face (Fig.source face), but the meshing result seems to ignore the two tubes (Fig.multizone). It seems that the face size is too large to detect the locations of two tubes, but no matter how I decrease the min size, it doesn't work.

Do you guys have any ideas what should I do to deal with it? Thank you!
