Multi-region with layers
 

Hi!!
i've been building a multi-region case with snappyHexMesh. After all the difficulties I am trying to add layers. I've trying to add layers to the tutorial "snappyMultiRegionHeater" in the surfaces between the bodies but it seems impossible to me.
Do you know how if it is possible to add layers to a multi-region case using snappyHexMesh??
Thanks!

You need to copy every region's mesh (one at a time) to constant/polyMesh and then run snappyHexMesh with only layer addition set to true in snappyHexMeshDict and then copy the resulting mesh back to its folder in the constant/regionName/polyMesh.
