[Wrf-users] wrf.exe running time error

[Eric Altshuler]

Hello Jesse,

Your problem is occurring due to your run_* settings. The total run time is the sum of all 4 of those namelist variables. In your case, the total run time is 1 day + 24 hr + 1440 min + 86400 s = 4 days. You only have boundary conditions available for 1 day. Keep run_days = 1, and set the other three variables to 0. This should fix your problem.

One question, why are you using only 7 vertical levels? Unless you're doing some kind of idealized simulation, that is not enough levels. The boundary layer can't be resolved, and there may be other problems as well. Many physics parameterizations may not work properly with so few vertical levels. I would suggest using at least 35 levels, perhaps more, since your inner nest has 3km resolution.

Hi,everyone 

I'm using WRF-ARW 3.1.1.The run time of my case is 24hr(2009-04-25_00:00:00 to 2009-04-26_00:00:00), 3 domains nested. 
Everything was fine until i ran wrf.exe,error msg are below 

Timing for Writing restart for domain 1: 0.57400 elapsed seconds. 
wrfrst_d02_2009-04-26_00:00:00 
Timing for Writing restart for domain 2: 0.58200 elapsed seconds. 
wrfrst_d03_2009-04-26_00:00:00 
Timing for Writing restart for domain 3: 0.45700 elapsed seconds.

-------------- FATAL CALLED --------------- 
FATAL CALLED FROM FILE: <stdin> LINE: 599 
... May have run out of valid boundary conditions in file wrfbdy_d01 

Then,what's the reason resulting in this problem. 
Any help will be appreciated.
