Can resistivity of electrodes be cahnged with Elmer

Post by rkarnam »

Hi,

I am new to Elmer. I have the following question.
I want to simulate the resistive plate chambers (RPC) using Garfield++. To create the electric field between the two parallel plate electrodes of RPC, I would like to use Elmer field solver. My question is: can Elmer create an electric field between two resistive electrodes, or it assumes the electrodes as simple dielectric materials? In future, can I change the resistivity of the electrodes, if I need to, and generate the electric fields between them?
If someone can answer for my question is grateful. Many thanks in advance!

Best Regards.

For what frequency are you running the simulation?

At DC the current in the plates is zero and the electric field between plates is the same as with perfect conductors. For a sinusoidal steady-state solution, the displacement current between plates results in a voltage drop in the plates and the electric field between plates is lower than for the DC case.

Yes, the resistivity of the plates can be changed by modifying the material properties. As stated above, this would impact only the sinusoidal steady-state case.
