[Gmsh] How to keep edge and cell together in partitioned mesh?

[Anthony Royer]

Unfortunately, I'm not able to reproduce the bug. If you recompute the partition, the error is still there and stays at the same place?

Here is an archive containing the partitioned meshes that I obtain with your geometry.

Is there a way to force surface edges to be stored together with their cells? In other words, I do not want an isolated edge whose only one point is connected to mesh and other point is dangling.
