Hello dear all,
I am running a 2D model with Jonswap wave condition.(instat=jons)
The grid is made by Delft3D, the mesh size is 1m in x-, y- direction.
the detail of bcfile is:
Hm0 = 1.62 fp = 0.178 mainang =
270 gammajsp = 3.3000 s = 20.0000 fnyq
I read some suggestion about the thetamin and thetamax to set up, my
main wave angel is 270, so i set up like below
thetamin = 225 thetamax = 315 dtheta = 15 (wave
bins=6 ) thetanaut = 1
Because wave bin isn't equal to 1, it will produce the wave
interaction like diffraction if I realized correct. I will build some
breakwater in the future, so I set the dtheta=15 )
When I run the case, no error happened, but the Hrms result is so
weird I think, like the attachment.
The wave main angle is 270 from the west but the wave height still
can't get high in the area (y=100m~120m).
From the Hrms distribution, it seems that the wave comes from NW.
How can I solve it to change some parameters?
Is it related to the parameters (thetamin, thetamax, and dtheta)?
Thanks in advance
