The ne does seem to wander around quite a bit deep in the model, rather than smoothly converge -- attached plot is for the last iterations 5 to 10 (i.e. from when the code declares convergence in the standard blr_... run onwards). Not so bad as the difference plot which Peter shows, but not great. The temperature convergence seems better. Suggests to me this may be a problem with poor convergence criteria/hysteresis, with the collisional cooling change just being the butterfly. there's also an unresolved drop in both ne and H+ around 8.5e11 cm in the first iteration, which might be worth trying to understand. Peter: It looks like there is a small thermal front in this model near the outer edge, though I derive this only from eyeballing the Te plot. They are quite common in blr models. It would also be a partial explanation of the jerky behavior of the code: gas near such a front will be quite sensitive to changes in cooling and/or heating since the curves are nearly parallel. It is however still worthwhile asking whether we are exacerbating the problem by writing the cooling terms in atom_leveln() the way we do. Robin: Yes, there is a temperature front exactly at the rear of the slab (it only appears in the later iterations). email exhange on this was around 2010 dec 22 - 24
