Hi, good day for everyone
Actually I'm creating one new case and have and little problem.
I would wanna please a little of help with this.
The SalidaIBI.txt is the .out after run the case.
This is the problem:
34 0000-58-00 00:00:00.00 1.538592E-03 8.674174E+03 8.674176E+03 1.258364E+13
(0502,081,8) 2.225654E+00 1.440689E-01 1.075710E+02 2.484856E+01
Found Error: 01 Line: 350 Source: ROMS/Nonlinear/main3d.F
Found Error: 01 Line: 298 Source: ROMS/Drivers/nl_roms.h, ROMS_run
Blowing-up: Saving latest model state into RESTART file
REASON: MaxSpeed = 2.5E+01
WRT_RST_NF90 - wrote re-start fields (Index=1,1) in record = 1
I guess that is for the bathymetry near at coast, because when #define WET_DRY, the model run with success.
Could please somebody tell me any suggestion or other form of run without use WET_DRY.
Thanks for read this and good day.

Re: Problem with Blowing-up, REASON: MaxSpeed = 2.5E+01
Sorry, i forget write this, about when I change the timestep at 10 seg, this is the problem:
103 0000-58-00 00:00:00.00 1.545792E-03 NaN NaN 1.258363E+13

I checked all the archives and haven't neither datatype NaN.

"WRT_RST_NF90 - wrote re-start fields (Index=2,2) in record = 1"
have you viewed the rst file?
use ncview or similar tool to quickly look in the file, see where the problem exists.

Thanks jcwarner for the support
Yes, I've.
I opened it and near at the coast, the values are biggest than the normal.
The u, v, ubar and vbar have the same problem and in the same location.
Do you think that I should change the depth of my mesh near at the coast for theses points?
Thanks

Re: Problem with Blowing-up, REASON: MaxSpeed = 2.5E+01
you need to do something there.
not sure what the bath looks like. maybe a little smoothing there. maybe increase visc2 a little.
maybe decrease time step. try a few things.

Thanks jcwarner, I tried changing the time-step until 10, but still have the same error.
I'll try a little smoothing in this zone following your suggest.

Hi, I'm facing the same error. When I use dt=30, max speed error; decrease dt to 10, 'kechar=nan,pechar=nan' error. Do you find any solution?
