It is clearer but still confusing, I am sure at some point I will have an AHA moment and feel comfortable with it.
I just can’t get a handle on why the overall thickness of these added layers vary with their original mesh cell size, the actual boundary layer doesn’t change thickness because some mesh algorithm decided that an area needs a finer mesh. But if you say the math works out regardless that these added layers vary in thickness over areas where the true boundary layer does not, then I believe you.
From what I can tell at this point, I want to try to get the yPlus value to average ~165 at the surface of the geometry. To determine a surface average, I can do surface mapping as in the above images and set a yPlus color range so that my eyeball tells me what the surface average is for the surface in view.
This seems very cumbersome, why can’t the postprocessor just let me select a surface (or my whole geometry) and then tell me what the yPlus, max, min, average, std deviation etc. values are for that surface?
I also assume I want the mesh slices in the mesh result to actually SHOW the 5 or x number of layers added in the layering process. So why are the mesh layers ‘missing’ in the middle image of my last 3 images (and actually it was over the whole wing as far as I can tell, not just near the trailing edge)?
