(RESOLVED) nest outputs with ndown have zero-values

Hi all,

I am trying to run a nested simulation with WRF using down.exe. I have followed the steps in the guide, and I arrive to run wrf.exe for the nested domain succesfully. However, variables outputs for the nest have all zero-values, except for the initial values ( I checked wrfinput and wrfbdy and they have non-zero values). For example I have attached results for surface pressure at time 0 and at time 100:





What might be the problem?

I have attached also the namelist.input I use to run real.exe, ndown.exe and wrf.exe

Thanks in advance for help!

Hi Caterina,
I'm not exactly sure what is causing the problem, but I did notice that you changed your radiation physics between the initial run and the nest run. You should keep those the same. Modify your LW/SW radiation to use the same scheme, and try running again. I suspect that won't correct the problem, though. If not, it appears that you may be running wrf-chem. If so, can you try to run a basic WRF run (no chemistry) with code compiled without the chemistry option and see if you still have the problem? Thanks!

Hi kwerner,

Thanks for your reply!
I finally managed to solve the issue by restarting from scratch, first with meteorology only and the adding also chemistry, and it worked.

Best!

Great! And thank you for updating the post.
