Ground
The Ground node implements ground (zero potential) as the boundary condition V = 0.
Ground means that there is a zero potential on the boundary. This boundary condition is also applicable at symmetry boundaries where the potential is known to be antisymmetric with respect to the boundary.
For some physics interfaces, also select additional Ground 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.
