Importing two meshes in fluent
Hello friends. I am using Fluent 14.0. I made two meshes i.e. outer and inner domain in ICEM around airfoil. I merged both domains in ICEM and then i opened it in fluent. now the problem is the boundary between two domains. I don't know what should i consider this boundary. I made it interface but it gives error. What should i do?

I read "merged"... When I do something like this, I use "Append case file", and after I create the grid interfaces.
I hope this helps you |
Thanks Agustin vila for your reply. You mentioned "Append case file" but i couldn't find this option in fluent. Can you elaborate a little.
Also, can I read both domains separately in fluent and merge there? I tried to read separately but the other one replaces. If any friend can help.. thanks |

Thanks Agustin. It worked but there is another problem for me. As one boundary of both domains coincides so in fluent I made these two boundaries as interfaces but it gives me error that " unassigned interface zone detected for interface 11" and same for interface 12. Interface 11 and 12 are for these coinciding mesh boundaries. I don't know what should I do. please help

Code:
Mesh > Zone > Append Case file |
Mr. Sijal, I followed your procedure. i read the inner domain first and changed the boundary condition of outer boundary to interface then same procedure for outer domain and changed it's inner boundary to interface. It seemed fine but it gives the same error. When i initialize, it gives these options
WARNING: Unassigned interface zone detected for interface 11 WARNING: Unassigned interface zone detected for interface 12 Error: Init_Flow: unassigned interface_zones interface 11 and 12 are the coinciding boundaries of two domains(which i think should be).. What should i do, please help. thanks |
After appending both meshes, create interface by selecting both interface boundaries (upstream and downstream) before initializing simulation...

yes it worked now. Thanks Sijal
