A `Side`

is a set of `Wires`

, to which is associated a `Surface`

. The first `Wire`

is the external boundary, the next `Wires`

define optional holes. These `Sides`

are used directly in 2D modelling, or gathered in `Skins`

for the definition of the boundaries of `Volumes`

in 3D.

side = sideset.add( Side(number, [wire1, wire2, wire3, ...]) ) side.setSurface(surface)

with

- In contact problems, the normal of a
`Side`

is the normal defined by its`Surface`

. - For rigid contact, the normal must point towards the interior of the material (as for curves in 2D).
- For
`Sides`

defined by their`Surface`

only (surface of revolution for example), it is allowed to define the`Side`

without any`Wire`

(the`Side`

has an implicit boundary: it is limited by the parameters $(u,v) = (0,0) \rightarrow (1,1)$ of the`Surface`

).
