Hi everyone

I wanna make AMI like this picture

it is just x-y side and i 'll make to 3D.

the circle is cylinder and I wanna rotate cylinder with AMI.

constant/boundary is

how can I solve it??

i guess you can't simply change boundary file. If you created your mesh using blockMesh then blockMeshDict has to be modified to take into account of AI interface. otherwise if you created this using some meshing software then you need to create an interface at the the boundary of the circle.

Hi,

you can not simply change the boundary file and add a new patch ... the topology of your mesh is defined by your meshing strategy and is stored in the point, cell and face files that are located in the polyMesh folder. If you really want to make an AMI, you have to use other techniques. Check out the tutorials that come with OpenFOAM. There you will find the answer.
