Revision as of 06:03, 23 June 2010
This page tracks activity in the WRF-Fire and related software development. All members of the fildfires communicty 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.
- A standalone driver for the fire code that is independent of WRF for diagnostics. See discussion.
- Take the winds from a given height, and set the height in the namelist.
- Take the winds from a given distance behind the fireline, and set the distance in the namelist.
- Gradual ignition from a point or a line without limitation on the initial radius. See discussion.
- Real test problem with real fire data at both fine and coarse resolution.
- Adding a canopy fire model for both passive (colocated) and running (not colocated with surface fire) canopy fire.
- Output of emissions products into WRF for visualization of smoke transport and dispersion.
- Connection of emissions products with WRF-Chem for online simulation of the evolution of smoke.
- Add fuel models & fuel modeling schemes.
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.
- Better quadrature for fuel left
- The quadrature is done separately on 4 smaller cells per fire cell. The interpolation of time from ignition to the smaller cells should take into consideration the case when some of the nodes interpolated from are ignited and some are not.
- REDIRECT Template:WRF-Fire-branch
- 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
- This affects the amount of heat output from the cell in the timesteps when the fireline crosses the cell.
- Input to the fire model the gradient rather than terrain height. See discussion. branch jm2/grad.
- Read the topography from a file in an ideal run. Fix/extend surface initialization in ideal cases to allow for defining surface properties like roughness, ground temperature, albedo etc., required by soil models and radiation codes. See discussion. branch adamko/surface
- Support hyperbolic vertical mesh grading in ideal run not only exponential. branch adamko/surface
- Set up fireflux test case branch jc
- Paper on the fire model in WRF-Fire.
- Paper on numerical methods in WRF-Fire
- Data assimilation
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.
