[Wrf-users] 3 nested domain stops without an error

[Κώστας Μυρωνάκης]

In my case, I use a single domain 500x500x30 in a Intel(R) Xeon(R) CPU
E3-1245 V2 @ 3.40GHz (Cores 8)
   Memory:  15960 MB.
It takes the 50% of memory ~= 8GB RAM and its complete in 4 hours (for 36
hours forecast).
In your case you need 16GB RAM minimum and more!
