- Main article: WRF-Fire. To get the software, see How to get WRF-Fire.
This page tracks activity in the WRF-Fire and related software development. All members of the community are welcome to get an account and edit.
Wish list
- Add your suggestions or plans here. If you want to comment on any of the items, please start a new section of the talk page and link to it here.
- Merge additional changes made independently in the WRF 3.3 release.
- Keep standalone model working.
- Add a canopy fire model for passive (colocated with surface fire) canopy fire.
- Take current time in ESMF form for ignition time computation to support adaptive time steps and ignition in restart runs. See discussion.
- Parametrize ignition startup. See discussion.
- Input fuel moisture from the WRF surface model.
- Better level set method: High-order ENO and WENO, discontinuous Galerkin.
In progress
- When you start on an item from the wish list, please move the item here and add a link to the branch where you work on it.
- Ignition from a given fire perimeter, with atmosphere and fuel consumption spin-up, by specifying ignition times. See discussion.
- Generate KML files for visualization in Google Earth. See discussion
- Real test problem with real fire data at both fine and coarse resolution.
- Better quadrature for fuel left: The current scheme is second order accurate when all 4 corners of a fire mesh cell are on fire, and exact when all 4 corners are not on fire. In the case when only some of the 4 corners are on fire, the only requirements are that the transition when nodes ignite is continuous and monotonous. In that case, the scheme may not be very accurate. A better scheme would be accurate in more cases and have natural invariance properties. branch jm2/mkim last commit branch vk/test
- This affects the amount of heat output from the cell in the timesteps when the fireline crosses the cell.
- Set up fireflux test case: branch fireflux, submitted abstract
- Data assimilation
- Dynamically determine midflame height and interpolate the wind there. See discussion.
- A standalone driver that is independent of WRF with I/O as WRF-compatible NetCDF files. branch jm2/driver_wrf See How to run the standalone fire model in WRF-Fire.
Done
- Move the item here when done and add a link to the contributor's last commit before the merge into master. Links to major milestone events can be also added to the timeline.
