Blow up before starting

#1 Unread post by javadi »

Hi all,

I ran the model but I have faced an error. This error can be a result of low Ram or CPU or the problem is in input file.

Best,

GET_NGFLD - free-surface western boundary condition, 1947-12-12 00:00:00.00
(Grid= 01, Rec=12, Index=2, File: croco_bry.nc)
(Tmin= 15.0000 Tmax= 345.0000) t = 345.0000
(Min = NaN Max = NaN)
GET_NGFLD - free-surface northern boundary condition, 1947-12-12 00:00:00.00
(Grid= 01, Rec=12, Index=2, File: croco_bry.nc)
(Tmin= 15.0000 Tmax= 345.0000) t = 345.0000
(Min = NaN Max = NaN)

looks like you have nans in your forcing file. you need to make them 0's or some relevant number.

Thanks for your response!

The problem is the open boundary!

Up to now, I had one open boundary in the south but now I have two open boundaries both North and west.

In this case, what should I do as both are close together in the attached Fig.

MOM6 can handle this case, with an open boundary inside the domain. ROMS is not set up to do that.

Would it be possible to extend your West boundary all the way to the upper land? (If I am reading the map correctly)?
Or rather, can you cut the domain from for only North boundary (where West boundary starts)?
But it is definitely your forcing that is the problem. Your file name indicates CROCO in it. I am not sure how compatible the tools from croco and the current ROMS are. That might be another issue to check for.
