Hi,
I am not sure if I understand your problem. I don't have knowledge of ICEM but u can change the BC in Fluent to Interface BC (mean data at this surface or plane or line will be shared by other surface or plane or line) as it is in Fig. 1. Mesh interface (in Fig. 2) is just a name of interface (User input) that u are creating from two interface zones. Form Fig. 2, Its seems that u have only one boundary as the interface BC. You need two boundary as interface to crate mesh interface. |

the problem is Am I reduce efforts to make (two Boundary) to meet Mesh Interfaces condition and work with Interface B.c. That is what i want to know Thanks in advance |

There may be other way to do also but I am sure about this (Interface BC)

Dear Banty
As I excepted , an warning appears during mesh check "WARNING: Unassigned interface zone detected for interface 34" And by searching this type of warning , I found this "To define an interface you will require two interface boundary conditions (one on either side of the interface)" check this http://www.cfd-online.com/Forums/flu...s-problem.html And I said before, we should meet Mesh Interfaces (two Boundary)condition thanks in advance |

Thats correct.
Once u have two boundary as an interface boundary condition then u have to defined the interface zone. plz see fluent user guide. http://jullio.pe.kr/fluent6.1/help/html/ug/node142.htm |
