[Gmsh] Question about attractor

[Harshad Sahasrabudhe]

Hi,

I'm trying to create a mesh inside a cuboid, such that the elements are
fine near a flat surface inside the cuboid. I tried using attractor field,
but it only creates fine elements at the origin.

I have attached the code and I'm not able to find out what I'm doing wrong.

Thanks,
Harshad
