[snappyHexMesh] SnappyHexMesh add Layer Only failed

fxzf · January 5, 2023, 07:19

Hi Foamers,

I have got a problem. When I am using snappyHexMesh, if I use snappyHexMesh castellatedMesh, snap and addLayers in one roll, then mesh is ok.

Code:

castellatedMesh true;
snap            true;
addLayers       true;

But I do castellatedMesh and snap first without layer, like

Code:

castellatedMesh true;
snap            true;
addLayers       false;

Then, I run addLayers only,

Code:

castellatedMesh false;
snap            false;
addLayers       true;

I cannot get any layer. So just want to ask if it is possible to use snappyHexMesh only to add Layers?

I did this before and it worked as expected.
You state that you "get no layers". What settings are you using for the layer generation itself, what does the log file say?
