hi FOAMERS,
im quite new to OPENfoam. Currently i am trying to do a RANS simulation of a flow over a wavy(sinesoidal) surface. this is quite similar to the tutorial periodic hill. however the inlet and outlet of my mesh (made in HEXpress) do not allign exactly. thus i want to implement the cyclicAMI boundary instead of a cyclic boundary.

i changed the type of all the 0-directory files to: cyclicAMI;

and i changed my boundary to cyclicAMI.

when running (parallel) i recieve the error code when when using decomposePar:
--> FOAM FATAL ERROR:
Unable to find initial target face

Im stuck with this for a couple of days now, does anyone know what i am doing wrong or is there any literature or examples applicable for this case.
