11 months ago Zongrun, The fuel load fgi is provided in two lines, the middle one is commented out. fgi = 0.166, 0.897, 0.675, 2.468, 0.785, 1.345, 1.092, !jc fgi= 0.166, 0.897, 1.076, 2.468, 0.785, 1.345, 1.092 1.121, 0.780, 2.694, 2.582, 7.749, 13.024, 1.e-7,
So effectively it is the same as: fgi = 0.166, 0.897, 0.675, 2.468, 0.785, 1.345, 1.092, 1.121, 0.780, 2.694, 2.582, 7.749, 13.024, 1.e-7
One fuel load value per each fuel category.

Dear all,
I am confused about the namelist.fire which is one of the input for the model. It seems fgi assigns mass loading of surface fuel for each fuel categoryies But the default fgi is looks like: https://github.com/openwfm/WRF-SFIRE/blob/f2dd6292cf96222d7851433f4243fb97980e4779/test/em_fire/namelist.fire#L29https://www.google.com/url?q=https://github.com/openwfm/WRF-SFIRE/blob/f2dd6292cf96222d7851433f4243fb97980e4779/test/em_fire/namelist.fire%23L29&source=gmail-imap&ust=1697136112000000&usg=AOvVaw0_WuB0dkfIGSojDYsXvJ1Y
It does not include all fuel categories (only 1-7). I used this namelist to run a case, the log file for the WRF-SFIRE case shows some burned mass for the Hardwood litter (9), Timber (litter + understor) (10). I am confused about why it happens.
Also, if I want all fuel categories to have their own fgi, should I uncomment the line: https://github.com/openwfm/WRF-SFIRE/blob/f2dd6292cf96222d7851433f4243fb97980e4779/test/em_fire/namelist.fire#L30https://www.google.com/url?q=https://github.com/openwfm/WRF-SFIRE/blob/f2dd6292cf96222d7851433f4243fb97980e4779/test/em_fire/namelist.fire%23L30&source=gmail-imap&ust=1697136112000000&usg=AOvVaw3E4bl5q2MKUl3HlfS82rXx
I can put part of the log for review.
