BLOWUP. REASON: MaxSpeed = 2.1E+01

#1 Unread post by Zeng »

Hello everyone! I am using ROMS to simulate the diffusion of tracers over several days. But I encountered the BLOW UP REASON: MaxSpeed = 2.1E+01 at early steps(71).

The maximum water depth of research area is 142m, the resolution of grid is 0.3km. I checked the rst.nc,I found the max speed in V(-22m/s), and the maxspeed occurs at the sea surface, close to the boundary and near the shore.(In fact, the maxspeed of both the seabed and the sea surface exceeds 20, but it is the highest on the surface.)

I have tried to find some solutions from forum. Such lke reduce DT to 10 or 5, define WET_DRY in the .h file, set the minimun depth to 2m. But all these are unuseful.The Courant number is small enough I think.

Code: Select all

Minimum barotropic Courant Number =  7.07604957E-03
 Maximum barotropic Courant Number =  5.34537607E-02
I created grid with Gridbuilder, and the values of rx1 and rx0 also meet the requirements.

Code: Select all

 Maximum grid stiffness ratios:  rx0 =   2.000000E-01 (Beckmann and Haidvogel)
                                 rx1 =   5.672658E+00 (Haney)
I have also export DEBUG=ON in build_rom.sh, unfortunately, I don't know how to degug it base on my poor ROMS konwledge.. The last solution I will take later is making the smoother bathymetry. I am confused, because I have already smooth bathymetry with Gridbuilder, need I use another methods to smooth bathymetry? if so, what kind of smooth tool should I use? Thank you for you attention, I would like to express my sincere gratitude for any kindly reply.

Hello, all guys, I checked my forcing files, I found the high values in Uwind and Vwind. So I guess the time I started simulation was during a typhoon, and my simulation domain is quete small which may leads the blowup. Now I would change the start time and try it again, I'm not sure if this help, or could you give me some other suggestions? Thank you so much! :mrgreen:

Maybe you need an even shorter timestep during a typhoon? The model does want a shorter timestep than you might think, especially with lots of vertical levels.

Dear Kate,
Thank you for your reply, besh wishes to you! :D

My grid has 15 layers in vertical direction. Actually, I don't want to simulate the situation during a typhoon, it's accidental. So I changed my start time to a calm day which is helpful, and now, with a DT of 20s, the mode has run successfully for several hours.

Kate, May I ask you another question? If I want to use bathy_smoother in Pyroms, but I only find some functions in the directory. From my understanding, we should run an executable file to smooth the bethymetry. Or, my understanding is incorrect? How can I use the bathy_smoother? Thank you again!

Re: BLOWUP. REASON: MaxSpeed = 2.1E+01

I'm afraid I'm not the expert on bathy_smoother, but my understanding is that there's more than one way to smooth bathymetry in there. I use an external program that filters bathymetry in a way to target only the roughest patches first, then I finish up with one pass of a Shapiro filter. There's no reason you couldn't do that in Python instead. There's also lpsolve, which solves the filtering in a different way, but can lead to bathymetries that ROMS doesn't like.

Or you can follow me in using MOM6 which doesn't need a bathymetry smoother.

Thank you, Kate, more information I have got. My simulation is still running which indicates that there are no obvious issues with bathymetry. So I'd like to keep stationary for now.

So I guess the time I started simulation was during a typhoon, and my simulation domain is quete small which may leads the blowup. Now I would change the start time and try it again, I'm not sure if this help, or could you give me some other suggestions? Thank you so much! :mrgreen:

Hi Junyang, I would like to know what software you used to check the wind fields. Thanks!

Hello, zduvims, sorry for my late reply. It's Panoply, the soft can quick read your .nc file directly.
