Electric Potential
The Electric Potential node provides an electric potential V0 as the boundary condition V = V0.
Because the electric potential is being solved for in the physics interface, the value of the potential is typically defined at some part of the geometry. For some physics interfaces, also select additional Electric Potential nodes from the Edges (3D components) or Points (2D and 3D components) submenus. For 2D axisymmetric components, it can be applied on the symmetry axis.
Boundary, Edge, or Point Selection
Beware that constraining the potential on edges or points in 3D or on points in 2D usually yields a current outflow that is mesh dependent.
Electric Potential
Enter the value or expression for the Electric potential V0 (SI unit: V). The default is 0 V.
Enter a value for the Contact work function Φc(SI unit: V). The default is 4 V.
