[swanmodel-users] Fwd: SWAN unstructured grid

[Nikhil G. <nik...@gm...>]

Hi Guys,

I am new to SWAN model. I have been trying to implement SWAN with
unstructured grid. I used Triangle to create a grid. Also, I have defined
boundary with markers like '0', '1', and '2'.

I am still trying to create forcing files, I wanted to see whether my grid
works for SWAN model and I faced two different errors. For running this
model, I used two different cases:

1. $BOU SIDE 2 CCW CON PAR 1.2 7.3 225

Model starts to run but ends up with error after 50 iterations and ends up
with an error. I do ot understand what this error means.

Error            :  Area of centroid dual is negative or zero in vertex
1
Error            :  Area of centroid dual is negative or zero in vertex
 20

2. BOU SIDE 2 CCW CON PAR 1.2 7.3 225

When I open the option of boundary forcing, simulation crash and give an
error

Terminating error: SwanBpntlist: list of boundary vertices could not be
completed

I would really appreciate if some one can provide an insight to my problem.

Kind Regards,
Nikhil
