yeah, plasma’s all about that hot, ionized mess of particles. When you’re running a CFD for jets, you’re really looking at how the electrons, ions and neutrals exchange energy, plus the magnetic field if you’ve got one. One quick thing: make sure you’re using a non‑equilibrium model – the electrons heat up way faster than the ions, so a single temperature isn’t enough. Also watch the ionization fraction; if it drops too low, you’ll miss the glow and the pressure forces. And don’t forget the radiative losses – in a high‑temperature jet, they can dominate the energy budget. Fix those three and your debug marathon will get a lot easier.

sounds like a good plan, that coffee is a must. I’ve skimmed the tables once, but the main thing is to keep the tabular data updated with the latest cross‑sections – the old ones under‑predict the line strength at 10 keV. If you re‑mesh the coefficients to the local temperature grid, the radiative losses will line up with the observed glow. Just make sure you keep the energy conservation check in the solver, otherwise the solver will start guessing the temperature and you’ll lose the realism you’re after. Good luck with the tweaking!
