How to mesh a closed body with unregular shape?

[fengzekang]

Hello developer and all:
If I want to mesh the voronoi meshes for a closed body with unregular shape, what should I do?
I noticed that we can mesh a cube(such as 1:1:1), and also we can define the mesh parameters to control the quality. But if I just want to mesh a 3D closed circular ring body, what should I do. I mean is there any example or the input files and commands?
Thanks a lot. Best regards.

Good idea for a future tutorial. Meanwhile, you can check out here for a few examples. You'd have to use -domain and optionally -transform cut to create non-convex shapes.
