Hi everyone,
I’m working through Workshop 1: Induction Heating of a Cylindrical Rod from the EMAG unit. I've attached a screenshot of my current geometry.

I'm struggling to make the geometry match what's shown in the PDF—specifically the 1/8th symmetry domain and the rectangular coil around the rod.

I searched and found that partitioning is needed, but I’m unsure how it affects the model or what exactly it changes.
Does it impact meshing or physics setup?

Any clarification would be super helpful!
