python3-dmsh binary package in Ubuntu Lunar amd64

 dmsh: "The worst mesh generator you'll ever use."
 .
 Inspired by distmesh, dmsh is slow, requires a lot of memory, and
 isn't terribly robust either.
 .
 On the plus side, it's got a usable interface, is pure Python (and
 hence easily installable on any system), and if it works, it produces
 pretty high-quality meshes.
 .
 Combined with optimesh, dmsh produces the highest-quality 2D meshes
 in the west.
 .
 Example capabilities:
  * Primitives
   - circle, rectangle, polygon
   - halfspace
  * Combinations
   - difference
   - nonconstant edge length
   - union
   - intersection
  * Transformations
   - rotation, translation, scaling
  * Local refinement
