[Gmsh] gmsh produces an overrefinement mesh

[Octavio Castillo Reyes]

Thank you for your answer.

The overrefinement is on points 9, 10, 11, 12, where a size dg*4 is
set. However,
if I remove the attractor field, the elements are larger at those points. I
do not know what I'm forgetting.

Can you give me some tips?

Best regards
