Thread split from Hornresp: When to use a PAR segment

So, the last four or five pages or so of this thread are just argumentative discussion over the suggestion that Hornresp should default to assuming PAR segments unless specified otherwise by the user? Wow ... :)

No. It's about modeling a pyramidal enclosure and then building a 2 parallel sided enclosure.

Now, HR defaulting to PAR instead of CON could help with the learning process. I'm willing to bet most 1st time users see the default CON segment and THINK it's OK to model all their 2 parallel sided enclosures that way.

CON should tell you if your enclosure will not look cone shaped internally (since folks like to build enclosures with wasted space), then don't use it.

Sometimes, things are simple as 1+1 = 3...🤣😂

For those people that don't get it,

1, +, and 1 are 3 individual items, words, spaces, etc

Shoot, maybe CON is OK since the 3 word also means a form of deception...thinking a 2 parallel sided enclosure will perform like pyramidal enclosure model is a falsehood.
 
In that case, you would be wrong!

but on the other hand it is okay for a parabolic horn to look nothing like a parabola. In the case of the parabolic horn you are in fact agreeing that it is the linear area expansion rate that defines it.

A parabolic ENCLOSURE can have ANY flare rate as long as 2 sides run parallel to each other.

A U has 2 parallel sides.

On an aeronautical side note...

This is why we SUPPOSEDLY have FedEx.

In 1962, Fredrick Smith entered Yale University for pursuing ecomics. According to some sources, he wrote a paper for an economics class, outlining overnight delivery service, on which he received a “C”.

He proved his professor (probably with a PhD) wrong with the creation of FedEx.
