Bug in CROCOv1.3 or CROCO_TOOLSv1.3 (BRY vs CLM)

Hi, I have a problem with CROCOv1.3 or CROCO_TOOLSv1.3

I am doing a simple modification of the Benguela case,

The issue is that the model runs with CLM boundary condition, but not with BRY, where it just stops.

STEP time[DAYS] KINETIC_ENRG POTEN_ENRG TOTAL_ENRG NET_VOLUME trd 0 0.00000 0.000000000E+00 4.3608853E+01 4.3608853E+01 3.7256284E+15 0

======================================= = = = STEP2D: ABNORMAL JOB END = = BLOW UP = = = =======================================

VMAX (M/S) = NaN IMAX JMAX = 1 68 IINT IEXT = 1 1

The the other changes are in crocotools_param.m

% % Grid dimensions % lonmin = -80; Minimum longitude [degree east] lonmax = -69; Maximum longitude [degree east] latmin = -33; Minimum latitude [degree north] latmax = -23; Maximum latitude [degree north]

% Grid resolution [degree] % dl = 1/6;


hmin = 55

closing the eastern boundary in cppdefs.h in cppdefs.h

undef OBC_EAST

setting the dimensions in param.h

  parameter (LLm0=65,   MMm0=68,   N=32)

and the timestep in

time_stepping: NTIMES dt[sec] NDTFAST NINFO 1440 900 60 1

Any idea on how to debug if the problem is the BRY file or something in the CROCO code?

Hi Andres, does the standard BENGUELA case work for you (with BRY). I just tried again and it does for me. In any case, It looks like you have a NaN value in your bry file.

Hi Patrick, ok, I will try to create the BRY with CROCO_TOOLSv1.2.1 to see if there is a difference.
