ath-4.3.4 No such file or directory
This looks like a wonderful program, but I am having a bit of trouble installing it.
I have installed ath4, including the .dll files ,changed the small.cfg file to find the right directory, etc. Whenever I run it, however, I get an error message of:
ath-4.3.4
No such file or directory
(notice the hyphen, not an underscore). I've even tried adding such a directory in a few places, but to no avail. Is this directory hard coded into the code? I have no idea what I am doing wrong. Any help would be appreciated.

Run it on the command line. "cmd.exe"

Ahh, that may be tough to find out. Please try this temporary release, it should manage the output directory better: http://at-horns.eu/release/ath4_4.3.5.zip
(No new functionality there yet - still in progress.)

Thanks. That worked. My CAD program weapon of choice is Freecad which was able to open the STL file without trouble although FreeCad doesn’t seem to support the .msh format.
Is it possible to make a horn/waveguide like a splitted donut to get a cutoff around 5000 Hz on a 1 inch driver?
Or does it need a kind of rollback?

Could you make a sketch? I'm not sure I follow, I see "rollback" as inherent to a "splitted donut".
I was thinking either a splitted donut or a ordinary horn (with rollback) but the latter is much more complicated to make
So the Q is. Will a splitted «donut» with a 1 inch opening glued to the 1 inch compression driver work as a horn/waveguide?

It will. Something like this, i.e. unbaffled?
Included are the project files for IB simluation (without a rollback), as well as the free-air shape in STL+MSH. Simulation for the free-air scenario (i.e. with the rollback) is not yet available, sorry.

This is for the infinite baffle. I only changed frequency resolution parameters in "solving.txt":
Control_Solver
f1=800; f2=16000; NumFrequencies=40
Abscissa=log; Dim=3D; MeshFrequency=25000; Sym=xy

Nice 🙂
What is the cutoff?
Autotechs Tractrix 1000 is 12 cm wide: TRACTRIX-1000 - Horns by Auto-Tech
And JMLC 2000 10 cm: http://horns-diy.pl/en/horns/jmlc/jmlc-2000/
I think it is better with a much smaller horn and a cutoff around 5000
Ale have very small horn: http://soundgate.net/product/NTE1.highend

There is no such thing here - you can see radiation impedance has no sudden drop, what's usually called cutoff. If I ever wanted to make a very small horn for 5 kHz xover (to a bigger midrage horn I suppose - not a very good idea, but OK), I would do it the way I showed, maybe a bit smaller, this was just a quick attempt. You can easily try it smaller and see what would you get - this is what the tool is for.
I'm probably just a complete command line dunce but I can't get this to work. I've followed the guide and this thread afaik. Created ath in the suggested dir, created the shortcut as described, have the output in the config file pointing to a new dir as suggested, and have "open with" set to notpad for the config file but am getting this. What am I doing wrong?

Isn't that a 32bit PC? I think the program is compiled for 64bit by default. I will look how to compile for 32bit. Otherwise I have no idea.

Is it possible to simulate the response of a routed waveguide lik Sagarmatha Duo from Bastanis have?

On a 1 inch baffle with a 1 inch hole then routed with a R 1inch round edge router bit?

It seems the program doesn't handle properly dimesions comparable to a throat diameter. I'll look at what the catch is. Anyway, this is the closest I could get. Besides the resonance (which is correctable in principle) it will beam at high frequencies. I'm not sure it's the right way to go...
- The program as it is now doesn't support radius as mouth termination.

Well, the beaming in this case is just a slightly worse than a typical 1" dome tweeter. Compression driver won't be as smooth but will have much higher efficiency. Maybe with some small driver like DE360 it could make a usable tweeter (instead of a 1" dome).
