Hello all,

I am going to calculate the forces on the helical-ended coils of a cos(teta) superconducting quadrupole magnet, applying magnetostatic and static stress.

I used the helical-ended coils in PMSM example, unfortunately, the coils can not be volume meshed and I received mesh generator error code: 401.it seems that the software can not mesh the circular ends. I have also tried with very fine mesh, mesh size 0.1, the mesh generation process last 2 days! but still the same error. I also tried to build the coils using 20-node bricks,  there are even more errors, would you please help me.

It is worth mentioning that using racetrack coils, to investigate the error source, the simulation runs fast and reliably.

Many thanks for your help, in advance.
