Problems with resistivity in the AC/DC Module in COMSOL 5.0

Please login with a confirmed email address before reporting spam

Hi,

I'm trying to simulate a current passing through a cylindrical grounding rod of 15cm of lengthburied in the ground. When I apply a potential equivalent to the current already applied previously, the impedance value changes. Attached got the distinct problem in two files "Test1 - Current" and "Test1 - Potential".
Interestingly, when I change the cylindrical ground rod to a spherical model, the simulations are performed seamlessly without changing the impedance.

Thanks,

Saymon
