Hello, 

I am simulating a coaxial cable (copper conductors, polyethylene dielectric) using ANSYS Maxwell 2D and the AC Conduction simulation type. The inner conductor is set to a voltage of 15 kV and the outer conductor is grounded. When I compare the capacitance and conductance simulation values to analytical values, the capacitance values match but the conductance values do not. I am using the following equation to analytically determine the conductance value per unit length: 

I replicated the same simulation using a different software and found that the conductance values matched. Is there something I am doing wrong? Should I be using a different solution type to accurately determine the conductance? Any help is greatly appreciated! I can provide additional information if needed.

I found a solution for this. The DC Conduction simulation type must be used and the Insulator/Conductor design setting needs to be changed.
