Dear all
I'm gonna use tri mesh around an airfoil which is supposed to rotate around its gravity center Therefore, I've created a geometry like the attached image. The bigger domain (called external fluid) and the smaller domain (called rotational zone) which includes an airfoil with prism layer around it.
The circular boundary around two zones is named as an interface.
The problem is when I import the mesh to fluent, it doesn't split the interface to two boundaries as (interface and interface_back). So I can't attach them since there is only one interface.
in 3D geometries, there is a parameter (Split internal wall) which is available for 3D geometries. Also, If I try to create a hybrid mesh (i.e tetra in the external zone and Hexa around the airfoil) I can merge the meshes using (merge nodes > merge meshes) icon in ICEM CFD, but for 2d geometry these options are not helpful.
I'll be thankful if you guide me to tackle this problem.

Save this file at two files, lets say innner and outer.

In the inner.prj project, delete outer part and similarity in outer, delete internal goemtry.

Now mesh them as your requirements, export them as separate file.

Now import any one mesh in fluent and then use append command to get second file.

Now got to interrface panel and create interface from two boundaries at the same location, overlapping each other, from both meshes i.e. inner and outer.

Thanks a lot Sijal.
Like always you are helpful.
For both meshes, I should name the interface B.C with the same name?
How about element size's on the interface between inner and outterB.C?
What is the append command? would you please give me a clue about it?

no. Give them name as interface side 1 and interface side 2.


keep the same size on both sides.

For append command see this pic
