4.7 Setting Up the Electric Field Model Parameters

You can set up the details of the electric field model using the Electric Field tab in the SOFC Model dialog.

Figure 4.7.1: The Electric Field Tab in the SOFC Model Dialog

Here, you can designate conductive regions and specify their conductivity, assign boundaries to be contact surfaces and specify the contact resistances, as well as specify which surfaces are grounded and which surfaces exhibit a current.

The Voltage Tap Surface is the surface that is grounded (i.e., $V=0$). The Current Tap Surface is the surface that current is being drawn from (i.e., $i$ is assigned a value).
