How to treat the interface for MRFSimpleFoam
 

Hi Foamers,
So far I am using conformal mesh for MRFSimpleFoam, now I want to use non-conformal mesh.

I am using Gambit for meshing, and I defined the faces as interface.

There are four interfaces,

What kind of Bc I need to use like AMI, GGI?

can I use AMI or GGI as follows,

constant/polyMesh/boundary

IF4
{
type ggi;
nFaces 13000;
startFace 40391000;
shadowPatch IF3;
bridgeOverlap false;
zone IF4_ZONE;
}

IF3
{
type ggi;
nFaces 26000;
startFace 40404000;
shadowPatch IF4;
bridgeOverlap false;
zone IF3_ZONE;
}

IF2
{
type ggi;
nFaces 23400;
startFace 40430000;
shadowPatch IF1;
bridgeOverlap false;
zone IF2_ZONE;
}

IF1
{
type ggi;
nFaces 13000;
startFace 40453400;
shadowPatch IF2;
bridgeOverlap false;
zone IF1_ZONE;

}

is it right way to define?

Thanks,
