Hi everyone,

I have made a multi region mesh in Salome. This implies that I have a solid and fluid region, each having their own mesh resolutions. At the interface though the polyMesh shows the following, implying that the interface has not been mapped yet:

Fluid side patch:

matl_top
{
type patch;
nFaces 2;
startFace 2252;
}
Solid side patch:

matl_top
{
type patch;
nFaces 211;
startFace 162155;
}

I plan to convert to type mappedWall manually (see link). Since nFaces is different on either side, I would require to do some kind of interpolation to get the correct mapping? Or is this directly taken care of by the mappedWall type ?

matl_top
{
type mappedWall;
nFaces // different on each side;
startFace // different on each side;
sampleMode nearestPatchFace;
sampleRegion fluid_region;
samplePatch matl_top;
}



Can someone point me in the right direction?
Thank you very much
