Hi,

I am trying to generate the tidal boundary harmonics (real and imaginary) for a regional model. While checking the BDY/bdytides.F90

The tide phase, phi_tide(ib)=ATAN2(-td%ssh0(ib,itide,2), td%ssh0(ib,itide,1))

Does it means that NEMO expecting the imaginary part with a negative sign in the input data, as

Im = - amp . sin(phase)

Now, I input the Imaginary part in the forcing file without the negative sign. Do I need to multiply with -1 ?

Thanks in advance Bijoy
