I would have guessed à priori that the factor was eight (one over the cube of the length-scaling). My numerical experiments with the attached simple cubic geometry aren't conclusive, but the number seems a bit short of that, though higher than 6. $ gmsh -3 cube.geo -clscale $CLSCALE | grep elements CLSCALE elements ratio 1.0 2 289 - 0.5 15 605 6.8 0.25 114 034 7.3 0.125 748 859 6.6
