No target curves and no optimizer.

No, it is just pre-defined high level without any circuits (you define frequency, Q, and dB).

I just ran the Windows insaller package, set the environment altitude as 3 metres and got this error message;

I cannot reproduce this.
You probably did something before that. Can you reproduce it?



If you can really reproduce it by only setting altitude to 3, try with debug build which shows more info on error and paste it again.

I didn't change anything else before changing the altitude. I tried it again and it didn't happen.

How would you suggest to model an aperiodic enclosure?

I would simulate it as Bass Reflex with stuffed port (low Qp and probably also low Qa).
I would also use port calculator for vent dimensions (or for number of Variovents).


To make it typical aperiodic enclosure set frequency to frequency of closed box at that volume. Simulation will show you typical aperiodic low impedance at resonance.
