[FLASH-USERS] ERROR: bad size of IONMIX4 energy group grid

[Reyes, Adam]

Hi Arthur,

You will need to match the runtime parameters that describe the radiation energy groups to the groups in your table(s). In your flash.par you have:

> rt_useMGD       = .true.
> rt_mgdNumGroups = 6
> rt_mgdBounds_1  = 1.0e-01
> rt_mgdBounds_2  = 1.0e+00
> rt_mgdBounds_3  = 1.0e+01
> rt_mgdBounds_4  = 1.0e+02
> rt_mgdBounds_5  = 1.0e+03
> rt_mgdBounds_6  = 1.0e+04
> rt_mgdBounds_7  = 1.0e+05

Guessing from the names of your ion mix tables you are wanting to mix the default provided 6 group he-imx-005.cn4 table with a single group h-imx-1grp.cn4. This is not supported and all opacity tables across species need to share a common energy grid. The users guide has more information: https://flash.rochester.edu/site/flashcode/user_support/flash4_ug_4p8/node149.html#SECTION061055000000000000000
