Wedge blocks with 6 vertices

[dklastiwka]

Is classy_blocks able to generate a wedge block with 6 vertices? This would be the case if the axis of revolve coincided with the radial coordinate of the inner patch.

No, unfortunately classy currently doesn't support non-hexahedral blocks.
Currently a workaround would be to create blocks with 8 vertices and correct block definitions in blockMeshDict manually.
Not very handy indeed; as this is the second time someone was asking about a wedge mesh, it might be reasonable to consider doing something in this direction...

Ok. Thanks for the reply. Wedge mesh capability would be very useful.

The thing here is that Operations don't care about their shape so a Wedge can be easily specified, also a Revolve where one edge of the face is coincident with axis of revolution - already with the existing versions. The machinery that assembles the blockMesh will not be too happy about that - edges, grading, count propagation, etc. If I removed zero-length edges check I'm afraid everyone that wants a pure-hexa mesh will miss messages about (possibly) serious errors.

Hello, I just thought I'd piggyback on this discussion, rather than create a new one. I'm considering using cb for a meshing project, but I have some tight crevasses (think a raindrop-shaped channel), where quadrangular blocks will always create some nasty elements in the narrow corner. so +1 for wedges.
