Say after several hundred tweaks to a model it will blank out the total volume. This doesn't appear to be caused by anything specific that triggers the error that I have noticed. Will try to replicate.

If I save the tlp and restart, then reload it is fine.

Any update to the offset in the curves <~60-80hz being displayed lower and 200Hz up being too high?

I'll see if I can find a reason for this, but it does seem very random!

This is to do with the stuffing model, I am currently looking at alternatives and will update if I settle on one...

Your latest release works without issues on Windows Vista64. I enjoy using your program and appreciate your efforts.
============
Could you add one decimal point of precision on the freq and SPL displayed on the bottom left corner in the Sound Pressure Level graph? Not a critical issue.

XX.x Hz

Value: [System = XX.x ]

===========

Do you have any ideas on how to model the "resistive nature" and "resonant nature" of several deep-but-narrow slot port as used on Onken style woofer cabinets? AkaBak is the current best simulator for this level of port air flow detail. Your models may not be suitable, but I'd appreciate your thoughts.

Thanks, that's good to know

Done. I'll release the update later today I think.

Erm.. This should just model in the normal way. If you have details of a design and accurate sims/measurements to compare I'll happily look into it.

OK this time when dragging a section out the "Volume" changed to "NaN" and no longer responds.

Also discovered when adding a new branch to the baseline model it's effects are not calculated now. Odd

Ok thanks. Still looking into this. Its hard to find the bug as it doesn't do it for me...

Do you just mean the volume isn't calculated. Or that the model (freq response) doesn't change at all?

Edit: I think I can see the problem here. It happens when you put a branch on the first element of the model. Is that correct?

That's what was causing me to hold back reporting this, it's that blasted where, when, what, how...

Correct. The added branch doesn't change the results regardless of volume, length or dampening.

It's useful reporting these things. Just hard to find sometimes! I'll hunt it down!

I know how to fix that branch issue, just need to get round to it. In the meanwhile, you don't actually need to use a branch on the first element as it is the same as moving the driver down the first element. Nevertheless I will fix it soon.

New update has just been uploaded:

- Added a decimal place to the graph cursor readout as requested.
- Fixed the bug where the branch on the very first element would be ignored.
- Changed the stuffing model to be more accurate (More at higher frequencies, less at lower).

Thank you for the update, is there a way of downloading the software directly? My wifi isn't working and I tried to download the .exe through my phone and transfer it over to my computer but the installer wants to connect to the Internet
