blow-up in first time step, using glorys and ERA5

#1 Unread post by lushilima »

Hi,
I am using Kate ROMS version (github - Jun/2021), trying to run with ICE_MODEL activated.
I am using ERA5 to atmospheric forcing and I used GLORYS to create the initial and lateral boundary conditions.
I solved a problem related with ERA5 time (hours -> sec).
But now I can't find whats is wrong in my inputs. The model blows-up in the first time-step, the rst file appears normal, and I verified that my lateral conditions that haven't NaN. :(
I'm running monthly.

No idea what your problem is, but maybe it is a good idea to check in the log file how the initial values are being read.. If they are reasonable or not.

And I'm not sure if it will affect your results but you did not close the southern boundary for temp and salt as you did for the other variables.

Hi rtoste,
Thank you for read and suggest this idea.
I realized that I was forgot to activate ice_model, and closed the southern boundary.
But I found another issue when I activate ICE, the model stop in first time-step, with a crazy salinity (and temp).
I can't find how to fix this bug: trouble in ice_frazil.....

You've got some crazy snow fall rates here. The ice frazil thing can be triggered by any one of fifty things that can go wrong. It's the most sensitive test for things like negative water thicknesses or strange salinities. At least you know where things are going bad: (i,j,k) = (292, 73, 30)

Dear Kate,
I fixed the snowfall rate, but still not running, and the simulation stops before the first time-step.
I tried to change the grid, initial conditions and boundary and still not working.
At that point where was pointed was in the middle ocean, and it not appear nothing wrong in the forcing data.

At the same time, I verified all the "Build_roms/" files and didn't found any possible problem with ice_frazil.
Which more things can I see? Do you have any suggestion that can be wrong?

Also, I tried to compile and run without ice module, and it stops also in the first time-step, and the problem indicates:

Code: Select all

DIAG temp ijk  NaN,  169,  35,  30,  1.
Appearantely it is a problem with temperature/salt data, but all the data seems OK.

I'm sure I've said this a number of times before, but it's time to develop some debugging skills. Plot the results after one timestep, try a shorter timestep just in case. Look to see what is going bad and where. If you want ice, I'd keep it on since turning it off isn't helping. The ice-free trouble isn't in the same place as the ice trouble, but where are they relative to features of your grid? Both are surface, right? Plot your surface forcings as seen by the model - stflux, ssflux, sustr, svstr.

I have a similar problem. when i nudging climatology field, including u,v,temp and salt, my model blow up, and my rst file have no valid data, but clim file and nudging coefficent file has been read without errors, i am unable to figure out this problem, Please help me, thank you in advance!

does it run without the clm nudging?
look at the entire output file, there might have been more info before the nan.

Thanks for your efficient reply. I found that there are many nans in my climatology file which is the reason for roms' blowing up. Now it runs well. :D
