[H2020]

Hello,

I am simulating the B-field distribution around wire bonds right now and have created a box with 600% padding in Z direction for my module. However, when I changed the padding and added a 300% padding in negative Z direction, my results changed drastically! Does anyone know what went wrong here?

Best,

As long as the region is sufficient enough to cover the whole field distribution you should get the same result for anything Region size above that region size.
But if you set the computational region such that it is not fully enclosing the whole magnetic field you will get a difference in results.
You can plot the fields and check if all the dominant field lines are enclosed in the region to figure this out.
I suggest you run a parametric starting from 2r to 20r region size .. (R basically be the 100% of the region size)
At some point, maybe at 10r, hopefully, you will not see the difference in the result after that.
*If the field results change significantly when the region size is changed, the region is not large enough.

Thanks Navya I didnt know about that. I ran a sweep and found out at which paddings the fields stop changing.
Best Regards!
