[snappyHexMesh] addLayersControls does not generate boundary layers

rinaldialberto · July 12, 2018, 05:20

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

Hallo Alberto,

set addLayers to true.

Code:

// Which of the steps to run
castellatedMesh true;
snap            true;
addLayers       true;

Regards,
Ricky

Thanks a lot Ricky,
