Hi Eric,
          Many thank for your reply, Eric. WRF doesn't create "ndown" executable when compiling NMM core instead of ARW core. You are correct , in my case the history files for the coarse domain are created before those for nested domain and I am not certain weather it is normal creation or a bug occurs. Does the warning message affect my results?

Thanks in advance
Ibra

NMM nests are one-way and have to be run after running WRF on the coarse domain and then running 'ndown'. Then run WRF on the nest using the lateral boundary conditions produced by ndown. As far as I know, the next WRF release 3.0 is supposed to have two-way interactive nesting for NMM, and hopefully a feedback switch (as is the case with ARW) that allows users to do either two-way interactive nesting or one-way nesting in a single WRF run without having to use ndown.

Hello wrf users, 

I am running WRF-NMM using WPS to preprocess my GFS real case. When I attempt to run the model on multiple domains, unlike on a single domain, warning message has been seen in rsl* files each time when opening a history file for the nested domain, the run was successful though. 
This is the warning message I see: 
WARNING in nl_get_adjust_output_times: adjust_output_times applies to all domains. First arg ignored. 


Has anyone experienced this problem? 

Mnay thanks in advance 
Ibra
