3D coil - mesh generation problems

I am trying to make a model of a 3D coil. To generate the geometries, I use the comsol script function helix3 as follow: h = helix3(0.003,30,4,5.25*4,50).
The geometries are generated without errors. To import them, I went to file -> impot -> geometry objects.
Now, when I try to generate a mesh (with any element size) I get this error:
Error: 4028
Failed to generate mesh for face.
- Face: 1
Failed to insert point.
- s1 value: 0.443619
- s2 value: 1
An empty cavity was generated.

Exception:

I try to increase the helix resolution from 50 to 100 and to 250 without any result. I found out that if I increase the wire diameter from 2mm to, let say 2cm, comsol manage to generate the mesh. However, the must have 2mm diameter.
Has anyone an idea how I could solve my problem? any help will be appreciated.
best regards,
