coupled model result

[redhat007]

i have coupled ROMS and SWAN for first time. With regard to related articles current will not effective effect on wave properties in the deep water. therefore i expected that wave properties would not be changed in deep water in coupled and swan (in standalone state) models in the deep water. In attached fig, which is in 200 m depth point, at first two model's results are coincided to each other but i don't know way after a while they became different Would you please help me we your experience to find this different reason. for example may it caused by swan set up (in part which we define dt for current transfer from ocean to wave model)? or not, this different is caused by some things else

Code: Select all

INPGRID CURRENT CURVILINEAR 0 0 195 345 EXC 9.999000e+003                 &
        NONSTAT  20061101.000000 15.25 DAY 20061231.236000

I will appreciate your reply
cheers

Dear
Unfortunately I can solve above problem, yet? Even with changing

Code: Select all

INPGRID CURRENT CURVILINEAR 0 0 195 345 EXC 9.999000e+003 &
NONSTAT 20061101.000000 15.25 DAY 20061231.236000

To

Code: Select all

INPGRID CURRENT CURVILINEAR 0 0 195 345 EXC 9.999000e+003 &
NONSTAT 20061101.000000 61 DAY 20061231.236000

I don’t have any other option in my mind . Should both model's results(swan standalone and swan coupled with roms) be same with each other in deep water for wave properties:?: Or such differencing is acceptable?
This is strange for me that results of second coupled model which started from 20th day of nov, are same as swan standalone model. That is while for first coupled model which start for 1th day of nov its result after 20th nov is different form swan standalone's result.
Would you please help me to understand what had happened?
