[Gmsh] Tips on large, tricky models?

[Max Orok]

Hello all,

I am trying to model a large, tricky problem in Gmsh.
Smaller cases succeed individually but larger cases are much more
difficult.
Does anyone have tips on "all-out" extreme meshing for cases that seem
intractable?

The small files start with "test_tube_with_stopper" and the larger files
start with "test_tube_small_box"

A brep is attached for the large case as the Boolean Delete took around 5
hours! It was sped up by setting the option "Geometry.OCCParallel=1" however.


Thank you for your time!

Sincerely,
Max
