I want to run a simple case of a rotor rotating in a cavity. I am facing the following issue.
The circular boundary is the interface I want to use for AMI.

This boundary is shared between the two volumes (Outer and inner), which I name separately in the python script.

The interface surface tag is however shared between the two volumes. When I run gmshToFoam, I get the following error.
"Cannot interpret multiple physical surfaces associated with one surface on line number 105"

So how do i get around this issue? I have attached the script I am using to generate the mesh.

TL;DR: Is it possible to generate AMI interface on a mesh created using gmsh?

Hello,

Unfortunately, the only way to assign two physical groups on the same boundary with gmsh (AMI interface) is generating individual mesh files for the rotor and the stator. Therefore, you have to create two separate python scripts, one for each of them.

Generating multiple internal walls using gmshToFoam

For joining them, you need to run gmshToFoam for both mesh files in two separate openfoam tutorial cases (you can use a "dummy" tutorial for the second one) and then run mergeMeshes as the following forum's suggestion:
