Very worried about the Horne stuff. Not so much that it means extra work, but if it is right then it instantly invalidates most the work done on electron precipitation as we have a massive none field alligned component that has so far been ignored...

Plus the energies involved means coding in brehmsstralung radiation. Worse, I'm going to have to learn how to spell it...

Anyway, chemistry routine is still slowly iterating between what I want and what it gives. The problematic reaction seems to be H2 + H2 in the presence of H2 creating H. At timesteps of (density/(1e7)), the numbers are too big at high density regions and the thing collapses. At density/1e8, timesteps are too coarse, leading to the reaction overreacting literally, leading to H2 tearng itself apart. Not a realistic case... density/(5e7) proves a little better, reducing the second problem without invoking the first, but isn't good enough. Now will try density/(2e7)...

Grodent20 finished quite happilly and read out. Unfortunately, Rimmer is down so it can't be analysed! Email sent to John, starmaster of starlink...

Should be noted the "Horne" stuff I refer to is one of the outcomes of the workshop I was at on friday/saturday, giving me the opportunity to sleep through some of europe's greatest modellers. Things to be studied...
