Multizone icem unstructerd mesh

Micheal

Hi i want to make a unstructered multizone mesh. I have made three zones in icem. but as i am exporting it as cgns it gives massage that "select a set of structered domains or one unstrctured domain." so, does anybody know that how to make multizone unsturcterd zones? i should see multizones in adfviewr. At present no matter how many zones i am making in icem it does not show those zones. Actually afview shows differnt sections based on elment types. I think the CGNS sturcture of icem may be differnt. Pls let me know if anybody kniows.

Thanku all.
