https://ngsolve.org/media/kunena/attachments/1658/meshing_bug.PNGHi!
I created geometry and meshed it using Ngsolve ngmesh = occgeo.GenerateMesh(meshsize.very_fine)

https://ngsolve.org/media/kunena/attachments/1658/elektrode_single.stp As you can see from the attached images, the edges at the bottom were meshed differently and wrongly. In my opinion, the meshing should be performed symmetrically at the bottom, which is not the case.
I was wondering what is the reason and how I can handle this problem. I attached the code to easily reproduce the result.
I ran Netgen on Window, The Output in the command line is given below:
