Extended Attack Suppression and Simulation Time

[kbrashem]

Running a fire simulation with extended attack enabled, I am having varying results, by as much as 2x the acreage by changing the SIMULATION_DTMAX parameter. Looking at the source code, I think the issue might lie in this line:

elmfire/build/source/elmfire_level_set.f90

Line 1016 in 6c27773

DT_DAY = (T - T_LAST_EXTENDED_ATTACK) / 86400.

Is setting the SIMULATION_DTMAX to 1 a requirement for suppression, or is this something where DT_DAY needs to adjust for varying timesteps? Thanks!

Thank you for the report. This part of the code base is relatively new and infrequently used so I will take a look to see if I can figure out what's going on.
