The tide level of my model does not match TPXO9

[tao]

I used the data from TPXO9 to generate a tidal forcing file. I defined the following cpp option and ran it for 90 days. There is a big deviation between the tidal level change of the site and the forecast data of TPXO9. Could someone please help me find out what the problem is? Appreciate any suggestions。

** Options for Tidal test case.

** Application flag: test_case
** Input script: test_case.in

My tide-related CPPs are

#define SSH_TIDES
#define UV_TIDES
#define ADD_FSOBC
#define ADD_M2OBC

You can try adding ADD_FSOBC and ADD_M2OBC.
