Re: computer allows more 100% supersaturation

Hello Ralph, hope you have time to answer since Matthias can't remember. See conversation below:

Me:
The question at https://forum.heinrichsweikamp.com/viewtopic.php?f=6&t=22050 Is still open. It seems to me that your code generates a warning level dependent on the kind of tissue. The slowest ...

Re: computer allows more 100% supersaturation

Hello Ralph,

Thank you for the answers.

If I understand correctly you have 3 warnings.
1) OSTC accepts excursions beyond the 100%, with warning give but also revoked once the dive returns inside the Bühlmann Limit again.
2) "second level" warning µ-bubble warning at 0.02 * ci + 1.0
3) "second ...

Re: on air dive with Buhlmann (no GF) then supersat = 1.17 is proposed

Hello Ralph,

The gravity constant what you mention is simply the METER_TO_BAR constant. I used the same parameter as in the Heinrich formula (1/10.19716)

Also I used ppWater = 0.06270 (same as in the code)

So this is not different.


BAR_TO_METER = 10.19716;
ppWater = 0.06270; % from heinrich ...

on air dive with Buhlmann (no GF) then supersat = 1.17 is proposed

Matthias proposed to send this email to the forum so more people can react.

I calculated a profile according to Buhlmann (no GF yet) and it seems that the pressures in some compartments exceed the allowed pressure.
This is for a profile that is recommended (simulation-mode) by the OSTC plus ...

computer allows more 100% supersaturation

I studied your code somewhat more to see when a warning is triggered.
Looing in code: https://bitbucket.org/heinrichsweikamp/hwos_code/src/default/src/p2_deco.c

If I look in your code from line 3747:
// calculate current supersaturation value (1.0 = 100%) of this tissue according to straight ...
