Segmentation Fault in DFI with 3 domain levels

Post by norulz » Sat Jan 13, 2018 9:43 am

Hi all,

I am getting a segmentation fault crash with V18.1.0 during DFI with a 3 level domain run (9km,3km,1km). Without DFI all seems to be OK.
A 2 domain level run (12km,4km) on a different machine with V18.0.1 seems to be OK with DFI = 3.

Has anyone else seen the same problem?

BTW the command line flag to change dfi setting is no longer --dfiopt but simply --dfi

SOLVED - Set a smaller time step for DFI

The domain is located quite far north so the default time step during DFI must have led to instability of the simulation.
I reduced the time step for DFI and now it's working OK
