Hi guys, i would kinldy ask you for some information.

1) how could i see on paraview the distribution of the layers obtained with "refineWallLayer" in the same way as done with the utility "nSurfaceLayers" when the layers are added with the "layer" option in snappyHexMesh?

2) which is the difference between adding layers with "refineWallLayer" and "add layer" ?

3) does the value of the y+ change when using layers obtained with "refineWallLayer" instead of "add layers" ?

4) which is the best way to add layers? "refineWallLayers" or "add layers"

thanks for the time spent for reading the post
