WRF User's Forum

Hi all WRF users,
I am a new WRF user. I have just installed WRF/WPS V3 in a linux box (gcc/gfortran compiler and basic nesting option 1). I have been able to run successfully most of the test cases. However, I have got into trouble when running the nesting case for the hurricane Katrina. The pre-processing WPS steps runs Ok and the intermediate and geo*.nc files for the two domains are generated correctly. The problem is that real.exe stops after processing domain 1 (check the FATAL ERROR message at the end).
Any advice..??
thanks a lot in advance
mtnez

Hi all WRF users ,

Ifound the answer to my previous problem. It was very easy.
Just add a second column (because I am using 2 domains) to the parameter parent_id in the namelist.input.

parent_id = 0, 1,

thanks

Hi everyone,

In my case, I was using tree domains, telescopic nesting, so in my namelist.input I had

parent_id = 1, 1, 2,

But it crashed with the error stated here. I solved the problem by adding the following line

grid_id = 1, 2, 3,

In the &domains section of the namelist.input file. Check this page for references: http://mailman.ucar.edu/pipermail/wrf-u ... 03259.html
