Hi! This week I wrote a Boyles law compensation and checked all the calculations to find the root of the differences of results against the original implementation.
I found that there is a difference between the code and papers in one of the CVA formulas. I need to add one more calculation, which will estimate the time at the surface required for the diver to fully regenerate. Another important thing, is that the Boyles law compensation seems to be just stupid. It scales the allowable gradients based on the nucleons radius at the first deco stop. The problem is, even very small difference in the tissue saturation or different way of ascent simulation can cause the diver to have the first stop sooner or later. Then, gradients are scaled against different radius, which has a huge influence on the total deco time. I will confirm it but for now, on one of the tests I had a minute of difference without Boyles compensation and 235 vs 289min with it on. That's way too much. -- Jan Darowski _______________________________________________ subsurface mailing list [email protected] http://lists.subsurface-divelog.org/cgi-bin/mailman/listinfo/subsurface
