I am trying to mesh a helical coil segment in ICEM CFD. My approach is to create a 3d block at the start of the geometry, and then extrude it along the center curve:
However, when I do this I end up with strange higher-order cells with many kinks, and some cyan lines (indicating that they are orphan lines, I believe?):
In the Extrude Along Curve settings, I ticked the Orient Axially option. If I don't tick this option, the blocks don't have these kinks but end up being orphan blocks.
How can I resolve this issue and create a mesh for this helical coil segment?
