Result: same, except XLONG and XLAT which are now set in ideal.exe and the fuel moisture variables, which do not exist in branch develop, and are not in registry packages yet

fixed dt only

In module_fr_fire_driver.F, there is a comment about “time – assume dt does not change”. Is that true or does the FFM work also with time varying dt?

Fixed dt only. Has not been a problem so far.

fire_ifun_end

• The call to fire_driver_em() has now fire_ifun_end = 2, where it used to be 3. According to the code comments in module_fr_fire_driver.F, fire_ifun_end = 3 has to do with initialization of time step. Is that skipped now or embedded within fire_ifun_end = 2?

fuel classes initialized for a real case

• How are the fuel classes initialized for a real case? It seems that the FM values are prescribed from the solution of the fuel moisture model? Could you document/explain that?
