Hi,
I use WRF V4.4.2 to run wrf.exe, then I got the error,

WARNING, FRC_URB2D = 0 BUT IVGTYP IS URBAN
WARNING, THE URBAN FRACTION WILL BE READ FROM URBPARM.TBL
USING DEFAULT URBAN MORPHOLOGY
WARNING, FRC_URB2D = 0 BUT IVGTYP IS URBAN
WARNING, THE URBAN FRACTION WILL BE READ FROM URBPARM.TBL
-------------- FATAL CALLED ---------------
USING 10 WUDAPT LCZ WITHOUT URBPARM_LCZ.TBL. SET USE_WUDAPT_LCZ=1

I attach my rsl.error.0000 file.

And I want to know how can I use the product CGLC-MODIS-LCZ (Demuzere et al.,2023) in WRF v4.4.2, OR only v4.5 can use it.
Thank you!

After add use_wudapt_lcz=1 in the namelist.input, new error occurred. Do you know how to fix it?

I found that this is a pretty large case with 5 domains. The RSL file doesn't provide any valuable information that can help to figure out what is wrong.
I would suggest that you start from running a single-domain case, and if that works, then you can proceed to run nesting cases.

I have run a test case using LCZ and it works fine. Below is what I did (namelist.input):

(1) activate LCZ: use_wudapt_lcz = 1;

(2) activate urban physics: sf_urban_physics = 1;

(3) use noah or noahmp land surface model: sf_surface_physics= 2 or 4.

Can you try with above options over a single domain? Please keep me updated about your progress.
 
Thanks for you answer! As you suggest, I run a two-domain case,and I set sf_urban_physics = 0,3,the case runs very well. When I run cases with 5 domains,I set sf_urban_physics = 0, 0, 0, 0, 3, error has occurred. But when I run cases with 5 domains, and I set sf_urban_physics = 0, 0, 0, 0, 2, it can run. Can you tell me the possible reasons?
 
Here is the new rsl.error.0000, and I want to know how to fix this warning:

WARNING, FRC_URB2D = 0 BUT IVGTYP IS URBAN
WARNING, THE URBAN FRACTION WILL BE READ FROM URBPARM.TBL
USING DEFAULT URBAN MORPHOLOGY

Thank you.

Please note that physics (except cumulus) are required to be the same for all domains. In your case, you need to turn on the same urban scheme in all your domains.
 
Thank you for your patience! I have another question. As you said, "physics (except cumulus) are required to be the same for all domains", I saw this in User Guide too, but I read "Variable sf_urban_physics is a multidomain variable, so a value should be set for each domain. Again it is suggested to use BEP only for the inner domains, with horizontal resolution of the order of few kilometres or less, to save CPU time." in a file named "Description of the modifications made in WRF.3.1 and short user’s manual of BEP ", so should I set the same value for all domains?
