[MITgcm-support] problems with OBCS

[? ??]

Dear Jody & Edward,
I have set an experiment with f = 0 , but v is still not zero. That really confuse me.
I am wondering how the northern and southern boundaries work in a 2D experiment, as periodic (as Edward says)?
No forcing is given except boundary tidal forcing (u at east/west boundary) in this experiment.
Thanks a lot.
Best,
Pengyang Song

And/or set f=0.   

Note that if you want f not = 0, then you are best to let v have non zero values.

Cheers,   Jody.
