[MITgcm-support] Problems with OBCS package

[Павел Лобовиков]

Hi folks!

I need to simulate the evolution of the tide in an ocean section with the
following topography (picture in attactment).

I've tried to use the OBCS package for this objective.

My grid has the following dimensions: (Nx,Ny,Nz) = (2600 x 1 x 384).

I have a file with a distribution of horizontal speed in time (inside is an
array with 1 x 384 x Time dimension).

My data.obsc file has the following content:

 &OBCS_PARM01
# This flag turns off checking and fixing problematic topography across
# open boundaries.
 OBCSfixTopo=.TRUE.,

 OB_Iwest = 1,
 OB_Ieast = -1,
 useOBCSprescribe = .TRUE.,
 OBWuFile = 'OB_WestU.bin',
 OBCS_monSelect = 1,
 &

But in the end I do not get all what I expect..

The velocity field immediately filled with sharp jumps (picture in
attachment).

What did I miss and do wrong?

My data file in attachment as well.


Thanks, Pavel!
