Let us say we have a round piece of straight copper wire 100mm long and 1mm diameter. With a copper resistivity of about 1.7e-8 Ωm.
At a frequency of DC, 10KHz, 10MHz, 100MHz.
The wire is supposed to have approx. resistance of 2, 2, 27, 82 All in milliΩ
I use EMPro FEM simulation to find the resistance. I tried material settings entry method –
Normal with surface conductivity correction
None of the entry method can gives correct answer.
How can I get correct answers in FEM simulations?
I was expecting at least material settings entry method, Surface resistance to give correct results.
What numbers are needed to correctly setup material settings entry method, Surface resistance?
Do I need to change these numbers for each frequency?
