Are those holes to mount the comp driver we see near the throat?

Yes, unfortunately, that is the way it is. In the final version, I plan to use smaller screws and some sort of semi-hard putty to make it removable if needed.

Hi!

I can't get this ATH software to work. I got right gmsh-4.3.dll on the program folder and whole program is located on desktop. First it just opens black window for couple of seconds and any tries after that just quickly flash the same window.

I'm running Win10, but i'm on the insider preview version. Would that cause the issue?

EDIT: Never mind. Found the answer. Run CMD first and keep running the software on that window. From all the pics i assumed it to have graphical user interface.

Open up a DOS window and run it from there.

It's not going to run properly if you double click on the program in Explorer, you need to run it from the command line.

1) click on the windows start menu

2) type "cmd.exe"

3) and then change directory to where you downloaded ATH4 and run it from there

Great tool mabat! Do you have any "Mesh." setting suggestions to speed up "first look" processing in ABEC?

Thanks Patrick. Got it working well. Awesome little tool this is. My only issue is now how to get .STL to editable solid in Fusion 360? Is that mentioned somewhere within these 72 pages?

Is there anyway you can pass through the chart axis range in your cfg? Would be good to set that 2% either side of F1,F3.

In previous posts I think you have suggested keeping the ThroatAngle at 0deg during simulation and then changing to the exit angle of the CD in real life. Is that still good practice?

Could you possibly comment on the below 90deg by 68deg results? What figures could be tweaked to improve the curves/response (if any)?

360mm x 260mm x 125mm
