A remark on over-constrained cells

Posted by Massimiliano Leoni at January 12. 2022
Hello, the documentation at https://docs.salome-platform.org/7/gui/SMESH/over_constrained_volumes_page.html says that over-constrained volumes are "volumes sharing only one border with other volumes". It then goes on to remark "In other words, the volumes having all their nodes on the external border of the mesh". Alas, these two definitions are not equivalent! As an example, consider a mesh containing three square cells one next to the other: the middle cell is over-constrained but it shares two borders with neighbouring cells. See the attached screenshot. Salome incorrectly detects only two over-constrained cells instead of three. While this example might look artificial, I'm having the same problem while meshing a complex geometry in which something similar happens. What do you think? Thanks in advance for any help, Massimiliano

I was able to correct the bug myself, I'd be happy to contribute the patch. At https://git.salome-platform.org/gitweb/ it says to contact OpenCASCADE, which I did, but I thought I'd report here too in case someone else can point me in the right direction. Best regards, Massimiliano

P.s. for some reason all newlines are lost when I post a message, I don't understand why...
