Axial
Symmetry
For 2D axisymmetric components, COMSOL Multiphysics takes the axial symmetry boundaries (at
r =
0
) into account and automatically adds an
Axial Symmetry
node to the component that is valid on the axial symmetry boundaries only.
When
Electric field components solved for
in the
Components
property for
The Electromagnetic Waves, Frequency Domain Interface
is set to either
Three-component vector
or
Out-of-plane vector
a constraint is added on the symmetry axis

Covariant formulation
. This formulation is used for all study steps, except Mode Analysis and Boundary Mode Analysis.
