What is the difference between Floating and Imposed potential in the electric application definition?

Mohammed Elamin_22169

When defining an electric application in Flux, one should select between “floating” and “imposed” potential. The difference between those two options in explained in the table below:

Potential of reference (on certain boundaries of the study domain)

Imposed	The electric potential V takes an imposed value at infinity (at the level of the infinite box) and on symmetry planes with a normal electric field* The value of the potential can be constant or described by a formula with input/output parameters.
Floating	The electric potential V takes an unidentified constant value at infinity (at the level of the infinite box) and on symmetry planes with a normal electric field*

* Caution: for 2D applications the electric potential is always set to 0 at infinity (at the level of the infinite box) and on the symmetry planes with a normal electric field.
