merge two meshe files

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

Hey,

let me take over Colinda in this case.

What you are experiencing is most likely due to incorrect boundary condition setup when you merged your 2 meshes in IGG.

In IGG, once you have imported your 2 meshes, you need to check the boundary conditions. This menu is found in the 'Grid' tab.

In this menu, make sure that the previous axial outlet (called HO4S....downstream_outlet) is not set to OUT. You have to set it to ROT. Same for the 2 inlet patches of your cf stage inlet, they should change from INL to ROT. 

Also, about your FINE/Turbo setup : how did you create it? I would advise to duplicate your axial setup, and link to the new mesh. This linking should not modify anything on your axial setup, except for the last patch that should now appear as a rotor/stator (it should not appear anymore as an outlet). The setup of the new cf blocks should be default values, to be set by you.

If all goes well, you should end up with only one inlet, one outlet, and a new rotor/stator interface.

Let me know how it goes.

Best regards,

Youri
