[swanmodel-users] Boundary effects

[Samantha M. <sma...@gm...>]

Hello,

I have a square domain that I'm forcing with a directional spectrum (all 4
boundaries have the same spectrum), but no matter which direction the waves
are coming from, our East boundary has weird results (see below) for the
mean wavelength. Significant wave height and direction look as expected
though.

I've changed the bathymetry to make sure there are no effects coming from
there.
Each of the 4 boundaries is treated the same.
I've turned on and off many physics (e.g. quads, triads, etc.), and none
seemed to help.

If anyone has some pointers for things to check or has run into a similar
issue, I'd appreciate any advice you have to offer :)

THank you!!
Samantha
