Dear All I'm trying to set up inundation problem in Gulf of Thailand. It's blowing up in few steps as shown error below with "DIAG speed trouble 46.2305206398322" For grid preparation: The minimum depth was -5m. I also attached the log file of this case. I dont know how to solve the problem. Please ...

Dear All

Thank you so much for your replying. After your suggestion, I rechecked all grid files and contact file.
The problem was from my contact file.
So, I fixed it already.

Thank you so much,

Dear All, I’m trying to run nested grid, It blows out since the beginning I noticed on DZmax and courant number on Grid02: Minimum X-grid spacing, DXmin = 1.00000000E-40 km Maximum X-grid spacing, DXmax = 5.12482819E+00 km Minimum Y-grid spacing, DYmin = 1.00000000E-40 km Maximum Y-grid spacing, ...

Hi All, I would like to stimulate free surface elevation for some part of SCS. My forcing functions are windU, windV, P, Tair, Q, rain,lwrad, and Tide from TPX7.0 So, my results look something wrong (as shown in the figure: free surface at the same time with difference scale). my LBC are list below ...

Dear all,

Thank you so much for your reply. I figure out my problem is
about the land-masking.

One more question on 'Zeta'. I am kind of confuse for the zeta.
I got all negative. I dont know why? Because I'm trying to get
the sea surface elevation.

Thanks again.

Now, i define as 'close boundary' for all.

GOT60.jpg Hi All I'm running ROMS for Gulf of Thailand (with dy=dx=5000m). It blow up after running for 2-3days. So I changed dt from 60 to 30. It can run longer but it still blow up. When I check my last file before blow up (as attached). It shows abnormal u,v around the western boundary of the ...

Hi I'm kind of confuse on climatology file. If I am not wrong. We can create the climatology file by using monthly data. Let's say. If I'm trying to run ROMS by starting this month (June1)and continue running, also update the forcing file everyday. . How can I prepare/add the climatology file? Thank ...

Hi All

I already get the output from ROMS (Qck file).
Then I'm trying to display the results (u) by using QGIS Software.
I found that the coordinate of the display is originated with (0,0).

My question is how can change it into the real lat-long coordinate.

Thank you so much.

Dear All, I'm trying to run ROMs by forcing with u,v,p components It was blowing up since the beginning. The error: Diag Speed Trouble Diag speed ijk I don't know why the max speed is so big Please help me to figure out the problem. Thank you so much Here is part of my log file ...

Hi Now,i'm trying to run ROM with forcing function wind from ECMWF products. And I'm getting this error: (some part) NLM: GET_STATE - Read state initial conditions, t = 5844 00:00:00 (Grid 01, File: SE_ASIA2_ini.nc, Rec=0001, Index=1) - free-surface (Min = 0.00000000E+00 Max = 0.00000000E+00 ...
