merge two meshe files

When you have separate meshes of different configurations, what is the purpose of combining these two meshes?

You can use the same mesh and run Fine Turbo.

You cannot couple axial and centrifugal templets in AG since they have different blocking strategy.

Thank you very much for your response. 

could you please ellaborate more ''You can use the same mesh and run Fine Turbo.''

Now, I wanted to run ax-cf compressor as an one unit. Previously, I was running them separately because I want to do some design alterations and save computataion power. 

Thanks

You can mesh both in AG. Row 1 can be axial compressor and row 2 can be centrifugal. In expert option change the mesh blocking strategy accordingly. Then use the single mesh into Fine Turbo.

Hi Sid,

Did you manage to combine both meshes into one?

If you still need assistance, could you please tell a bit more how you made the meshes? Did you use AutoGrid5 and then run the simulation in Fine Turbo? Which version are you using? 

If you used AutoGrid5 you can import both meshes in IGG and set the rotor/stator interface there. It is very important in that case that the outlet of the first row is on the exact same surface as the inlet of the second row. Often that is not the case if the space between both rows is very limited. The outlet region of the first row may then overlap with the inlet region of the second row. This can be taken care of by a z-constant line when initially meshing the rows separately, to create a block at outlet/inlet. In that way the outlet block of the first row and the inlet block of the second block can be removed and the remaining meshing can then be connected.

Dear Colinda,

Thank you very much for your explanation. Indeed it worked. I need some further guidance. As soon as I import my mesh into Fine, things are bit chaotic not very nicely structured. For example in rotating machinery section id number for row 1 of cf stage and ax stage were similar(10). Instead of that id for row 1 for cf stage should be last row of my ax stage + 10. Anyhow, I changed it manually. Now problem is when I go to initial solution tab interface for my cf stage id's are not being recognized. The new generated id numbers are not present. For example, in the following picture id 100 is my channel exit, which in principle should be outlet of cf stage but it is still recognized as outlet of my ax satge and inlet of cf stage. Could you please guide me here.  

With Regards

Sid
