The A–Vm Formulation
Mixed formulations are also used in computational electromagnetics. These formulations use different formulations that are more suitable for specific computation domains. One of the most famous mixed formulations is the
A
–V
m
formulation, which is a combination of
The A Formulation
and
The Vm Formulation
. In this
mixed formulation
,
The A Formulation
is used to model current-carrying domains, and
The Vm Formulation
is used to model the air gap and other nonconducting domains. The two formulations are coupled on their common interfacing boundaries. The
A
–V
m
formulation is used by
