Not getting a symmetric magnetic field for a symmetric modal in ANSYS Maxwell

      Dear ANSYS Support Team,
                I hope this email finds you well. I am writing this to seek your assistance regarding an issue that I am facing while doing Transient analysis, for a tube(100mm length) and a coil placed inside the tube, in ANSYS Maxwell. There are two such models are shown, viz.
      1. Single Stage - tube and middle coil.
      2. Multi Stage - tube, middle coil, and two end coils(connected in series).
      For the excitation of coils, I've used a current dataset obtained from an experimental setup.
      The magnetic field along the inner surface of the tube (i.e., along distance at a particular time) is unsymmetric and has more ups and dips even though my modal is symmetric. I've shown the magnetic field distribution for both models.
      Why is it unsymmetric? I want to get a peak at the center and symmetrically reducing curve to either side.
      I would greatly appreciate it if you could assist me in getting a symmetric curve.
      Thank You in advance.

      Hello, firstly it's important to ensure that the geometry of your model is perfectly symmetric. Secondly, the meshing of the model plays a crucial role in the accuracy of the simulation results. A poorly defined mesh can lead to inaccurate and unsymmetrical results.
