Hello WRF community,
I hope everyone's doing well. Currently, I'm trying to run WRF simulations (WRF v 4.5.2) using ndown.exe for 3 domains. where my innermost domain d03 will simulate urban physics. So, accordingly, I followed the steps mentioned for ndown in the WRF user guide (Welcome to WRF User’s Guide! — WRF Users Guide documentation), for the d01 to d02 and similarly, I'm doing it for d02 to d03.However, when I was trying to execute the 3rd WRF simulation using d03 as single domain and wrfinput and wrfbdy from ndown, it started showing error:
So, I just enabled sf_urban_physics for both d02 and d03 before the second ndown.exe and followed the ndown steps again. It did not show any error afterwards while running the wrf.exe for d03 as single domain.
Is this correct or am I missing something?? It would be nice if anyone could explain why this happened?? Also, is it ok to run ndown for more than 2 domains??
Sincerely,
Tanmoy
