[FLASH-USERS] [EXT] Hydrogen EOS/opacity tables

[Eddie Hansen]

Can you send the par file you're using (after switch from Al to H)?

You may ultimately have trouble accurately modeling cryogenic H with IONMIX
tables. They're somewhat limited at low temperatures (< 0.2 eV) and can
result in some of the errors you mentioned.
