[swanmodel-users] Long-term WW3 boundary conditions

[Jin L. <jin...@gm...>]

Dear SWAN users,

I am using WW3 open boundary conditions for SWAN. After I wrote the monthly
WW3 spectral with the SWAN format, use the following command:

BOUNDNEST1 NEST 'ww3_201801.dat' CLOSED
BOUNDNEST1 NEST 'ww3_201802.dat' CLOSED
BOUNDNEST1 NEST 'ww3_201803.dat' CLOSED
...

The problem is that every file is too big (about 900 MB), I may need to use
the "BOUNDNEST1" for 41x12=492 times if I run the SWAN for 41 years. I was
wondering how you set the long-term WW3 boundary conditions? Do you know
any other alternative options? Many thanks.

Kind regards,
Jin Liu
