[MITgcm-support] advection of ice-melange

[Mainak Mondal]

Hi Martin,

There is a subglacial plume at the eastern boundary. It is coming up to the
top and making a surface expression. There is the u component of velocity
that should push the ice-melange. In the SEAICE_OPTIONS , I have already
turned on the
#define SEAICE_ALLOW_FREEDRIFT

In the data.seaice I used
# SEAICE parameters
 &SEAICE_PARM01
 SEAIcewriteState =.TRUE.,
# SEAICE_initialHEFF= 0.5,
 SEAICE_EPS =1.E-8,
 SEAICEuseDYNAMICS =.TRUE.,
 HeffFile='Heff2.bin',
# AreaFile='Area1.bin',
 SEAICEadvHeff=.TRUE.,
SEAICE_no_slip = .TRUE.,
 &

 &SEAICE_PARM03
 &

Regards
