One-Way Nesting, Zeta Dropping

[yuchengzhang]

There are issues for the child domain when I run the model.

One major problem is the surface elevation keeps dropping for the child domain.
Initial condition for Zeta:

After 1 day:

u and v behaved OKish:

When I plot the graph for zeta using rst file for the refined domain, there is a clear jump at the boundary. The graph shows the top right corner of the child domain:

The discontinuity also happens for salt, temp, u and v but to a less extent.

Anyone has any idea what might be causing this issue? The output log is attached below.

The problem had to do with ROMS version, I updated the version from 3.7 to 4.1 and ran the model, the problem disappeared. So, it's highly likely ROMS 3.7 had a bug somewhere and it got fixed. Anyway, the lesson is, run the model with newer version....
