Problem when running 1km nested domain

[antonianna]

Hello everyone!

I have 3 domains (1 parent=15km, 1 nested=3km and 1 nested=1km) but I have a problem when running 1km domain (domain 3). When i put the max_dom=2 then the wrf.exe is running correctly. I do not know whats wrong with the 3rd domain. I have attached my namelist.input file and an image to show the location of the nested domains. This is an one-way nesting. Do you have any idea to solve this problem?

Hi,
Without seeing the error logs, I would guess that the issue is due to the placement of d03 inside of d02. It needs to be further away from the boundaries. Take a look at this page, which discusses best practices for setting up your domain.
