This has been a request for a long time. See for example


So far, my solution is to parse the .msh file and compute the node
connectivity and neighbor list each time. I proposed a
$Neighbors$/$EndNeighbors$ optional section so I can save time by doing
the search once, generate a new .msh file with that section and then use
that information instead of re-computing it each time.
