Trouble with snappy and boundary layers
I have a problem with boundary layer addition producing strange "blobs" on edges of the geometry. The snapping works well but the "blobs" appear after adding layers.
I'm attaching images from the stl file and from the snapping procedure, both with and without BL.
I have also attached blockMeshDict and snappyHexMeshDict.
We have managed to produce more complicated meshes before with these settings and the .stl file seems to have high quality??
Unfortunately the mesh is quite large (5M cells).
yes, this problem is very well known here. there is no chance to "smooth" the surface from those blobs. i think you have to wait till the new OF version comes out and brings the new snappyhexmesh with the featureEdgeLines tool.
Thanks Wolfgang for your replay. Do you know why the blobs appear? Can I avoid them?
no sorry, no idea. i have to live with it. actually I am moving on to another (commercial) mesher that meshes geometries mainly automatically with full control influence of me. it also creates a nice boundary layer. It can do hex and prism BL. and it is not that expensive (like gridgen e.g.). its called castnet.
ok, thanks for helping me. Maybe I do the same and take a look at that commercial mesher.
I have some strange problems with layer generation in snappyHexMesh. Would be great, when somebody knows how to face the problem.
I attached a photo and my snappyHexMeshDict below.
Thanks in advance!
