Hi everyone,

I'm an OpenFOAM's new user and I am trying to simulate the typical case of a laminar flow around a cylinder with heat transfer (3D).

My question is what type of BC I have to use in order to get the exchange of informations between the interface air-solid.

I was thinking to implement in my script constant/cylinder/polyMesh/boundary a BC called mappedWall but I don't know what sampleRegion and samplePatch stand for.

CYLINDER_INTERFACE
{
type mappedWall;
sampleMode nearestPatchFace;
sampleRegion ;
samplePatch ;
startFace 3780;
nFaces 288;
}

Is there someone who can help me, please?

best regards,

Christian
