Dear users,

I ' m quite new to OF and I have to deal with this problem: I have a cyclic pipe that I merged with a divergent nozzle like in the figure below.
After merging I have for the patch in section B two names, one derived from the nozzle and the other one from the pipe.
I would like to map runtime the field in section B (internal patch) to section A.

I tried to use cyclic boundary conditions for the pipe but it doesn't work beacuse I think that I can't impose a boundary condition on an internal patch.

So I tried in another way: changing the boundary file and putting

sectionA
{
type mappedPatch;
nFaces 8;
startFace 45368;
sampleMode nearestPatchFace;
sampleRegion region0;
samplePatch sectionB;
offsetMode uniform;
offset ( 0 0 0.096 );
}

but it doesn't work.

Any idea of how I can fix my problem? Thank you very much!
