Hi there,


I compute the wave vectors by creating some new variables.
I was wondering why the arrows near the shoreline are overshooting the line?
Here I attach my wave diagram.



Thanks for the help~

Have a nice day~

Hi
Are you sure to well compute the vectors?
What is the background layer?

Regards

Hi,

I compute the wave vector by creating two new variables in blue kenue:
dir_x = sin (DMOY*PI/180)
dir_y = cos (DMOY*PI/180)

Then, I create vector by using dir_x as component U and dir_y as component V.
Did I make any mistakes in computing the vectors?

The background layer of my wave diagram is the wave height distributions.

Thanks for your help.

Hi,
Are you sure DMOY is computed with the north (Y axis) as reference?
If not, you should switch sinus and cosinus...

you could probably check this by drawing the direction layer instead of wave height

Hi,

I already check my DMOY. Here is my result.

Hi
Vectors and scalar are in accordance...
What are you expected at the boundary?
I'm not a specialist of TOMAWAC but it seems to me that the reflextion on solid boundariez is not include...
Maybe an explanation of such values for DMOY?

Regards

Hi,

I'm actually first time computing wave model with TOMAWAC. So, I am not familiar with TOMAWAC as well. For the solid boundary, I used the free boundary condition where its written in TOMAWAC manual that this type of boundary is assumed that the coast absorbs completely the wave energy (no reflection). I dunno whether is it because of this reason, my wave vectors are overcrossing my coastline??

Thanks

Hi,

I don't really see the problem with your vectors crossing the shoreline. These vectors represent the wave direction at the boundary (and since the vectors begin at the boundary, they necessarely cross the shoreline). If you used the free boundary condition, which corresponds to waves propagating beyond the domain (and nothing else enters it), that seems to me pretty normal.

Best regards,

Hi,

Thanks for your reply. I am new to TOMAWAC and I just wanted to know is there any parameters in tomawac that can use to include the reflection effects at the solid boundary?

Hi,

At the moment, the effects of reflection on structure cannot be taken into account in TOMAWAC.
If effects of reflection on structures (or diffraction) are important in your study, you should better use a phase-resolving model (as Artemis).
