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 -------------------- !!!!

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?
