addLayersControls does not generate boundary layers
 
1 Attachment(s)
Dear all,

I am having problems in creating boundary layers around a simple extruded geometry.
I tried to play around with nSurfaceLayers, expansionRatio, finalLayerThickness, minThickness,relativeSizes.

Is somebody able to help me in creating the bl?

I attach the blockMeshDict, the stl geometry and snappyHexMeshDict I am using.

Cheers
Alberto Rinaldi

Hallo Alberto,

set addLayers to true.

Code:
// Which of the steps to run
castellatedMesh true;
snap            true;
addLayers      true;
Regards,
Ricky
