It goes like this.
1:Firstly I installed WRFHydro,coupled WRF;
2: But why when I run the case given by the official website, wrf and wrfhydro coupling case. Inside the result I generate, there is no *.LSMOUT_DOMAIN file and *.RTOUT_DOMAIN2 file and *.CHRTOUT_GRID2 file? What should I do?
3: I'm sure the WRF model is running with no errors reported. Checking the rsl.error.0000 shows a successful run.
4: Case URL: https://github.com/NCAR/wrf_hydro_nwm_public/releases/download/v5.1.1/
front_range_CO_example_testcase_coupled.tar.gz
5:Since there is a segment error when running wrf.exe, I changed "time_step=15" to "time_step=2" in namelist.input of the provided case; and it ran successfully. It worked.
6: Regarding hydro.namelist, the main control output is as follows:
!!!! -------------------- MODEL OUTPUT CONTROL -------------------- !!!!
! Specify the output file write frequency ... (minutes)
out_dt = 60
Specify the output file write frequency... (minutes) out_dt = 60 Specify the number of output times to be contained within each output history file... (minutes) (integer)
(minutes) out_dt = 60 !   SET = 1 WHEN RUNNING CHANNEL ROUTING ONLY/CALIBRATION SIMS!!!!
SET = 1 WHEN RUNNING   SET = 1 WHEN RUNNING COUPLED TO WRF!!!!
split_output_count = 1
SPLIT_OUTPUT_COUNT = 1 SPLIT_OUTPUT_COUNT = 1 ! Specify the minimum stream order to output to netcdf point file ... (integer)
SPLIT_OUTPUT_COUNT = 1 ! Note: lower value of stream order produces more output.
order_to_write = 1
Flag to turn on/off new stream order... (integer) ! Flag to turn on/off new I/O routines: 0 = deprecated output routines (use when running with Noah LSM), !
0 = deprecated output routines (use when running with Noah LSM), ! 1 = with scale/offset/compression, ! 2 = with scale/offset/NO compression, !
! 2 = with scale/offset/NO compression, ! 3 = compression only, 4 = no scale/offset/compression (default)
io_form_outputs = 4
io_form_outputs = 4 Realtime run configuration option: !
! 0=all (default), 1=analysis, 2=short-range, 3=medium-range, 4=long-range, 5=retrospective, !
! 6=diagnostic (includes all of 1-4 outputs combined)
io_config_outputs = 0
Option to write output files at time Option to write output files at time 0 (restart cold start time): 0=no, 1=yes (default)

CHRTOUT_DOMAIN = 1 ! Netcdf point timeseries output at all channel points (1d) !
                             Output netcdf file control CHRTOUT_DOMAIN = 1 !      0 = no output, 1 = output
CHANOBS_DOMAIN = 0 ! Netcdf point timeseries at forecast points or gage points (defined in Routelink) !
                             Netcdf point timeseries at forecast points or gage points (defined in Routelink) !      0 = no output, 1 = output at forecast points or gage points.
CHRTOUT_GRID = 1 ! Netcdf grid of channel streamflow values (2d) !
                             Netcdf grid of channel streamflow values (2d) !      0 = no output, 1 = output
                             NOTE: Not available with reach-based output.      NOTE: Not available with reach-based routing
LSMOUT_DOMAIN = 1 ! Netcdf grid of variables passed between LSM and routing components (2d) !
                             Netcdf grid of variables passed between LSM and routing components (2d) !      0 = no output, 1 = output
                             !      NOTE: No scale_factor/add_offset available
RTOUT_DOMAIN = 1 ! Netcdf grid of terrain routing variables on routing grid (2d) !
                             RTOUT_DOMAIN = 1 !      0 = no output, 1 = output
output_gw = 0 ! Netcdf GW output
                             output_gw = 0 !      0 = no output, 1 = output
outlake = 0 ! Netcdf grid of lake values (1d) !
                             Netcdf grid of lake values (1d) !      0 = no output, 1 = output
frxst_pts_out = 0 ! ASCII text file of forecast points or gage points (defined in Routelink) !
                             ASCII text file of forecast points or gage points (defined in Routelink) !      0 = no output, 1 = output
Although the wrfout*** file is generated, only the *.LSMOUT_DOMAIN file and the *.RTOUT_DOMAIN2 file and the *.CHRTOUT_GRID2 file are not generated, what should I do?

你好,我遇到了同样的问题,耦合模式下的案例只有wrf的输出,而没有wrfhydro的输出,请问你解决问题了吗?
