[Gmsh] Question about Full Thorus

[Ruth V. Sabariego]

Hi Paolo,
That syntax is deprecated. Before it was possible to explicit region numbers for the layers.
You should remove it.

Regards,
Ruth

I have still one question, since I have not been able to understand the role of the number that have been highlighted in bold in the script. Playing with the script I have understood that the first 10 is the number of "slices" that divide the angle but I have tried changing the 73 and the mesh was not changing. Changing the 1 I was getting errors. Could someone explain me the meaning of those numbers?
