"OUT OF BOUNDS" messages in fort.98

Hi,

The wrf.exe I was running recently was forced to stop halfway, and the rsl files show "forrtl: severe (174): SIGSEGV, segmentation fault occurred". Meanwhile a file named fort.98 was created in the directory, and it contains a number of messages, all of which are the following:

**** OUT OF BOUNDS *********

It seems that no point exceeded cfl=2 when the model stopped. I am wondering what caused this problem and how I can solve this problem.

Attached is my namelist.input file and rsl.error.* files.

Thanks for your help.

Lili,
Your namelist.input looks fine.
Which version of WRF are you running? And the forcing data? How long did the model run before it crashed? Can you find any error message in rsl files?

Hi，

Thanks for your prompt reply.

I am running WRF 3.9.1.1, and the forcing data is NCEP North American Regional Reanalysis (NARR). The model ran for 13 days before it crashed. Except "forrtl: severe (174): SIGSEGV, segmentation fault occurred", I think there is no other error message in rsl files.

If you have saved wrfrst files, please restart from the most recent wrfrst file and save the output at every time step. Then look at these wrfout files to find when and where the first NaN appears. This will give you some hints what is wrong.
If the model can successfully run for 13 days before it crashed, it indicates the forcing data should be fine. I am suspicious that the physics in the model may go wrong.

Thanks for your suggestion. I will try it later.
