Blow up after running for 2-3 days

[jitraporn13]

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 domain.

Please give me some advise.

Thank you so much

I think the problem is your masking.. can you write your boundary condition

[jitraporn13]

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

Try to using open boundary, did you smooth yout bathymetry?

You have shown us surface stress, not velocity. What surface forcing fields are you using?

I think you effectively have two separate domains due to the land masking - right?

Hi
As I look on the domain not defined properly 'land/sea (mask)'.
Cheers

Those surface stresses seem way too high to me. What forcing are you using?

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.
