I was talking to nejc, but I didn't ask for permission, do you want me to delete it?

I need the mesh and this sketch represent exactly what I'm looking for

no dont worry

thx ^^

@otaolafr i find my research difficult, do you know how to create still coupled cyclicAMI boundary conditions?

why the personal tag tho.

check #810161483903401984

no one answered

please answer

i did

please tell me how to create cyclicAMI boundary conditions

that are still and fluid freely passes through it

Create cyclicAMI boundary conditions

If you're too lazy to describe your problem, why would you expect others to take the time to answer a vague question?

Or even ask follow-up questions for clarification

i put in snappyhexmesh's patchInfo all the necessary inputs for cyclicAMI. The stl file is edge which creates faceType boundary and therefore in patchInfo I type neighbourPatch edge_slave. But upon doing that snappyhexmesh complains saying I can't put a name that is the same as one geometry in snappyhexmesh

help!

So it was an XY problem

You can show your file here, so others can check it

i want "edge" to be a cyclicAMI boundary condition

After a quick look:

{
        name edge1;
        patchInfo
        {
            type                   cyclicAMI;
            method                 faceAreaWeightAMI;
            neighbourPatch         edge_slave;
            transformType          none;
            matchTolerance         0.001;
        }
        constructFrom patches;
        patches (edge);

    }
    
    {
        name edge2;
        patchInfo
        {
            type                   cyclicAMi;
            neighbourPatch         edge;
            transformType          none;
            matchTolerance         0.001;
            method                 faceAreaWeightAMI;
        }
        constructFrom patches;
        patches (edge_slave);
    }

- ``neighbourPatch`` should be ``edge2`` and ``edge1``, respectively. - there is a typo on the edge2 type => `` cyclicAMi;``

alright your solution worked, thanks

Does anyone know why my residuals wont go any lower than this the first sim is with 4 cores second with 6 and the mesh is attached aswell as the freecad OF file https://cdn.discordapp.com/attachments/400697259819270145/1388237544113705112/Screenshot_20250627_151703.png?ex=68604076&is=685eeef6&hm=c475034808bf3bb4e58ae5d470bd4252e82211182b6a564f33d4c1418192a241& https://cdn.discordapp.com/attachments/400697259819270145/1388237545531375707/Screenshot_20250627_151722.png?ex=68604077&is=685eeef7&hm=560a51b081da2e1c2d9bdc913587e94097284898adfff1ae96bb5e4f5fb419d2& https://cdn.discordapp.com/attachments/400697259819270145/1388237546214920344/we.png?ex=68604077&is=685eeef7&hm=6829e6fe0d2f0e804114494b8f1aa6ade52de2a3c97fe79bbe86f8e82c67bac8& https://cdn.discordapp.com/attachments/400697259819270145/1388237546718498816/image.png?ex=68604077&is=685eeef7&hm=0888df857d318857e687fcf10a74fc91f8356dacd383b2bcc3bc241fe6efb965&

I am new to CFD and this is the first sim that has done this

Please let me know if you need any details as well!
