hello
I want to create a permanent static magnetic field over the whole region while using transient solve.Could you tell me how to achieve it?
And I have another question.I built a coil ,and set a terminal.When i use the current source to drive it,i find the current is distributed unevenly around the coil. What's wrong?

Hello,

1. Please use helmholtz coil to create the field in transient solver.
2. It seems like there is eddy effect on this coil. Please use stranded round-shape coil and make the solution region larger.

Hello GL,

 

          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.
