Multizone unstructerd mesh frm icem in cgns format

Michael

Hi i want to make a unstructered multizone mesh in icem and export in form of cgns file. I have made three zones in icem. but when 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 adfviewer. At present no matter how many zones i am making in icem it does not show those zones. It only shows differnt sections based on element types, like volume and surface elments. I think that CGNS sturcture of icem may be differnt. Pls pls let me know if anybody kniows.

Thank you all.
