import mesh error/warning
 

While importing a mesh from patran all groups got imported as seperatre zones in Fluent but surprisingly I notice some warnings shown below and the two following zones got split into two additional zones. Can anybody help me to say why it is happening so. I want to avoid them happening

Thanks in adavance Laxminarayana
