Please see Talk:WRF-Fire_merge_testing for permanent notes.

The version to test is branch fuel-moisture-model currently at commit c1cedfc7eba28a2ed

The baseline is WRF4 branch develop currently at commit 0f296f9c0f674f9

When either branch advances we have to retest - after any fix in fuel-moisture-model (I will let you know), and, after we are done, we will have to forward branch develop to current WRF4 and merge it into fuel-moisture-model. For this reason (and to reduce confusion), I am trying to organize the tests in a way that they are really easy to rerun without modifying any files - separate clones for different compilation options and separate copies of test/em_fire directory for different test cases.

The namelist.input and namelist.fire with variables that turn the fuel moisture model and fire on are in test/em_fire_rain/rain. The description of the namelist variables is at Fuel_moisture_model#Configuration. Other features from WRF-SFIRE are not carried over - only the fuel moisture model.

Who is doing what:

Angel - WTF, parallel testing of both branches for identical results, all test cases in test/em_fire
Adam - a real problem
Jan - fixing, selected testing as needed

How to test

Record also unsuccessful tests, when fixed, replace by the final result and include link to the commit used
All tests should be reproducible by checking out the commit noted, which should include all data for ideal runs
For real runs, please link to the datasets to be reproducible

What needs to be tested

Fuel moisture model off vs. WRF4 baseline, with and without fire, did we change anything?
reading fmc_g, is it doing what it should?
Fuel moisture model on, fire on, is it doing what it should?
Serial and parallel execution with different numbers of CPUs, are the numbers same?
WTF as specified in WRF testing requirements
All ideal cases in test/em_fire and some real

Jan's test results

All kingspeak runs are in /uufs/chpc.utah.edu/common/home/u6015690/merge and run on node kingspeak11 (nodes can be different).

Baseline

Angel's test results

All kingspeak runs are in /uufs/chpc.utah.edu/common/home/kochanski-group3/farguella/merge and run on node kingspeak11 and kinspeak12. All the compilation are done using ifort serial (13), nesting 0.

Branch develop vs. added-fmc_g

The branch develop and branch added-fmc_g are in kingspeak in folders WRF-Fire-merge-develop and WRF-Fire-merge-added-fmc_g respectively. They are tested in order to see the first new functionalities of adding variable FMC_G in WRF4 baseline. Tests are from list in https://www.openwfm.org/index.php?title=Porting_WRF-SFIRE_fuel_moisture_model_to_WRF4#Testing_to_be_done.

fire_fmc_read not present in namelist.input

One can observe that both simple hill simulations are exactly the same running

diff WRF-Fire-merge-develop/test/em_fire/wrf.log WRF-Fire-merge-added-fmc_g/test/em_fire/hill_tests/original/wrf.log -I Timing

which returns

10c10
<    alloc_space_field: domain            1 ,              344571608  bytes allocated
---
>    alloc_space_field: domain            1 ,              345388824  bytes allocated

Therefore, the only difference is in the allocation size as expected.

However, the new branch added-fmc_g is creating new variable FMC_G taken constant value of fuelmc_g from namelist.fire all over the domain. Changing value of fuelmc_g in namelist.fire changes the value of the new variable FMC_G.

fire_fmc_read present in namelist.input

Setting

fire_fmc_read=0

and poblating FMC_G variable in wrfinput_d01 using ncreplace in Matlab. The branch added-fmc_g uses the new FMC_G in the simulation from new wrfinputs. Tested using:

Constant FMC_G field of 0.07: WRF-Fire-merge-added-fmc_g/test/em_fire/hill_tests/fmc_07.

Constant FMC_G field of 0.08: WRF-Fire-merge-added-fmc_g/test/em_fire/hill_tests/fmc_08. Exactly the same results that branch develop which was taking the information from namelist.fire file.

Random FMC_G field: WRF-Fire-merge-added-fmc_g/test/em_fire/hill_tests/fmc_rand. Gives the progression with random bumps as expected.

Slope FMC_G field: RF-Fire-merge-added-fmc_g/test/em_fire/hill_tests/fmc_slope.
