ndown problem

Discuss the nesting capability within the model itself and any problems you might have run into.

ndown problem

Postby cmgd5 » Wed May 25, 2011 3:26 pm

Hi
I am running the wrf model for 2 domains and I'm using ndown for this purpose. However, I have a problem running ndown and I'm lost about the solution. I can generate correctly the input files to run the program, but after running ndown the following error appears in rsl.error file:

-------------- FATAL CALLED ---------------
FATAL CALLED FROM FILE: <stdin> LINE: 355
program ndown: opening too many files
-------------------------------------------

I'm new using wrf model. In this sense, I really appreciate if anyone can help me with this problem.

The namelist.input file that I have been using is:
