[snappyHexMesh] Snap to the surface without surface refinement?

sk11 · May 10, 2018, 05:31

Hey All,
I have a problem meshing a simple truncated cone surface. I want to introduce a pressure drop using the porousBafflePressure on this surface by creating Baffles using createBafflesDict. Since this BC works with cyclic patch, I think it is not possible to mesh using refinementSurface. Because it will create a patch of type wall. So I used only refinementRegions near the geometry. Will it be possible to snap the meshes to the surface, if I use only refinementRegions? Or is there any ways to mesh to the surface and change the patch type to work with porousBafflePressure?
Please find the CreateBafflesDict, SHMDict and the screenshot in attachments.
Many thanks,
Sarath

I could refine to the surface and snap to surface by adding faceType internal; option under the patchinfo. This option considers the surface as an internal face and makes only null patches which will be deleted by snappyHexMesh by default.
