Extended Attack Suppression and Simulation Time #59

Open kbrashem opened 3 months ago

kbrashem commented 3 months ago

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: https://github.com/lautenberger/elmfire/blob/6c27773fed7c3f258b68b063793339e1c7bcb6de/build/source/elmfire_level_set.f90#L1016 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.
