This wiki page explains how to call qgis2fds from external scripts for programmatical use.

Executing qgis2fds from a script

QGIS comes with a tool called QGIS Processing Executor which allows you to run Processing algorithms and models (built-in or provided by plugins) directly from the command line without starting QGIS Desktop itself, as described here.

For example, you can execute qgis2fds from the command line in Linux by typing:

$ qgis_process run "Export to NIST FDS:Export terrain" \
    --PROJECT_PATH="golden_gate_local.qgs" -- \
    distance_units=meters area_units=m2 ellipsoid=EPSG:7019 \
    chid="golden_gate_local" fds_path="./fds" \
    extent="-122.491206899,-122.481181391,37.827810126,37.833676214 [EPSG:4326]" \
    pixel_size="5" \
    origin="-2279076.207440,1963675.963121 [EPSG:5070]" \
    dem_layer="US_DEM2016_local.tif" \
    landuse_layer="US_210F13_21_local.tif" \
    landuse_type_filepath="./Landfire.gov_F13.csv" \
    fire_layer="fire.shx|layername=fire" \
    wind_filepath="./wind.csv" \
    tex_pixel_size="1" \
    nmesh="4" \
    export_obst="1" \
    project_crs="EPSG:5070"

as you would from within qgis2fds user interface.

Note that, in this example case, you need to prepare a preconfigured template as the golden_gate_local.qgs to facilitate the setup of the data sources.
