Hi,
I am running nested domains with dt 27, 9, and 3 seconds of dt.
However, I’ve noticed that the second domain is stable with a dt of 9 seconds also, but the nested simulation is
unstable with dt 81 27 9, so I want to use as dt 27, 9 and 9.
I’ve tried to set timerefx and timerefy = 1 in AGRIF_FixedGrids.in something like
1
20 20 30 30 3 3 3 3
1
20 20 30 30 3 3 1 1
0
and I made the corresponding changes in the croco.in (dt=27), croco.in.1 (dt=9), and croco.in.2 (dt=9).
But it crashes (using MPI). Should this work?
By mistake I used and AGRIF_FixedGrids.in file with values
1
20 20 30 30 3 3 3 3
1
20 20 30 30 3 3 3 3
0
And it runs. Which dt is being used. The one defined by the croco.in.2 file or the one set by the file AGRIF_FixedGrids.in?
The information is redundant, and in the case it works, contradictory.
Any insight is appreciated.
