I am setting up a case for a SOEC-cell and I was wondering what the contact surfaces and resistances in the electric field tab are defined. Like what surfaces are relevant for me to choose in this option. Unfortunately, I could not find any documentation about this.
Thank you for your help.

When setting up a case for a SOEC-cell in Fluent, the Electric Field tab allows you to define various parameters related to the electric field model. In this tab, you can designate conductive regions and specify their conductivity. You can also assign boundaries to be contact surfaces and specify the contact resistances. Additionally, you can specify which surfaces are grounded and which surfaces exhibit a current. You will need to select electrically conductive regions from the Conducting Zones and Conductivities list and set their conductivity. For contact surfaces, you can select them from the Contact Surfaces and Resistance list and specify their resistance. You also have the option to select a voltage tap surface, which is the surface that is grounded. Please see 32.3. Using the Solid Oxide Fuel Cell With Unresolved Electrolyte Model for more information.
