How to use vert_refine_fact=2 with ndown.exe (or real.exe)?

Hi guys! When I use ndown program and set vert_refine_fact=2, I always get the following error:
taskid: 0 hostname: login05

I also meet this error when I use real.exe, so I want to ask: Why does this error happen? and what should I do to solve this problem? Thanks!!!

Hi,
Based on this error, it looks like your version of WRF may be a bit older. Can you try using the latest release (v4.7.1) and see if you still experience the same issue? Thanks!
