Each segment has various properties and user-set parameters.
|
||||
This chapter provides a basic reference to these items.
|
||||
Which properties and parameters are available differs for each segment.

Most segments require a measure for the cross-sectional area.
|
||||
For ease of use, this can be entered as either the radius

\begin_inset Formula $r$

or cross-sectional area

for the left node or
|

\begin_inset Formula $R$
|
||||
\end_inset
|
||||
|

for the right, e.g.
|

\begin_inset space ~

\begin_inset Formula $rL=0.2$

To avoid interpretation errors, they should be entered as keyword arguments,

e.g.

\begin_inset space ~

\end_inset
|

|

|

\begin_inset Formula $\mathrm{ConeDuct}(L=1,rL=0.2,rR=0.3)$
|

\end_inset
|

|

instead of
|

\begin_inset Formula $\mathrm{ConeDuct}(1,0.2,0.3)$

|
||||
Once a segment has been constructed, its parameters become properties and
|
||||
can be adjusted later on.
|
||||
For example, say 'duct' is an instance of the class PrsDuct and we want
|
||||
to change its radius.
|
||||
Then
|
||||
\begin_inset Formula $\mathrm{duct}.r=2$
|
||||
\end_inset
|
||||
|
||||
will set it to
|
||||
\begin_inset Formula $2$
|
||||
\end_inset
|
||||
|
||||
m.
|
||||
Retrieving any measure of cross-sectional area is also possible:
|
||||
\begin_inset Formula $x=\mathrm{duct}.D$
|
||||
\end_inset
|
||||
|
||||
will retrieve the diameter and save it to
|
||||
\begin_inset Formula $x$
|
||||
\end_inset
|
||||
|
||||
.
|
||||
\end_layout

|
||||
On top of that, segments contain calculated properties.
|
||||
These are listed in Table
