[Wrf-users] ndown error

[atu hozi]

Hello dear users,

I am fairly new to wrf and I am working over the wrf online tutorial on the
Katrina case study that uses one way nesting employing  ndown However,
after getting the necessary input for ndown from real.exe and renaming
wrfinput_d02 file to wrfndi_d02, I am getting an error when I run ndown.exe
that says,"program ndown: opening too many files."
Your help is highly appreciated.
