Comsol extrude along line strange behavior

Please login with a confirmed email address before reporting spam

Hi,

I'm currently designing a planar transformer with PCB windings. The windings are obtained from sweeping the winding track surface cut along its center line. In my chosen geometry, each corner is formed by an arc of 90°. The second enclosed screenshot shows the center line, with the desired trajectory.

However, as it can be seen on the resulting geometry once the winding is swept along the center line, the arcs angles are not constant at 90° as expected, but tend to increase with the distance with the center limb. Is there a misuse of the Extruder function that leads to this result?
