I post for the first time.

I'm currently researching around the Ahmed Body; a simplified model of a car.
I cut the grid, but I'm struggling without having a layer in the vicinity of the body.
I thinking about various parameters, but I would appreciate if you could give me a professor because I don't know the cause and solution.

Attach blockMeshDict, snappyHexMeshDict, a snappyHexMesh log, an image of calculation area and an image of a part without the layer.


and, I put the STL file of Ahmed body at the following URL

Hi Masatoshi,


Increasing the featureAngle in addLayersControls over 90 may solve your problem.
With the iglooWithFridges tutorial, a featureAngle of 120 creates layers around the cylinder corner.
