Compute current through a cross section of my metallic structure

Question

Hello,

I am trying to obtain the total current that goes through a plane in my structure, as shown below :

I've found the .out and .os files where currents are saved, but I have them sorted by label (1, 2, 3, 4, 5, …), and not by geometry, even if I see that the coordinates are written.

1. What is the "good" method to compute the current through my red surface here ?

2. Should I sort the triangles by coordinates in order to find the ones that cut through my surface, find the currents, and try to integrate them along each triangle size ?

2 bis. In this case, should I use the centered value of current, or corners ones, or … ?

Thanks a lot !

Hello,

Thanks for the input. It works nicely. I'll try further tests !

Hello Degleve,

To calculate the current flowing through the plane, you might use the edge port as shown below.

After defining the edge port,  you can add one load (whose resistance = 0) to the port and check the current of the load in the POSTFEKO.

Please see the attached model.

Best regards,

Jaehoon

Hello Jaehoon,

How are you ? Thanks for the repply.

. Computing the circulation of H is indeed an easier way, but still a bit convoluted, no ? Also, I am not so confident in the veracity of the near field magnetic field. I'll give it a try nonetheless.

. Otherwise, are there no options to easily obtain the currents ? This is weird !
