CFD Online Discussion Forums - [snappyHexMesh] snappyHexMesh : Layers on patches

Hi all,

Edit: I am trying to prevent layers from collapsing at inlets and outlets as in http://www.cfd-online.com/Forums/openfoam-meshing-snappyhexmesh/90204-boundary-layers-inlet-outlet-pipe.html

The method described in the above works normally, but I cannot get it to work in parallel. Any ideas?

I first run snappyHexMesh with the layering step turned off, then change the inlet/outlet patches from type 'wall' to type 'empty' in all 'boundary' files (processor*/2/polyMesh/boundary), then execute snappyHexMesh again with only the layering step turned on.

I received the following errors upon executing snappyHexMesh for the layering step:

Code:

[7] --> FOAM FATAL ERROR: 

[7] in patch:procBoundary7to3 : Local size of patch is 14286 (faces).
