Hi all,

I am trying to set-up a simple 2D wave case using SFLOW however I am having trouble setting it up correctly. Attached is the description of the simple domain I am trying to set. Beach is on the left side and Offshore on the right side.

Essentially the trouble I am having is to be able to point the waves towards the beach.

In DiveMesh, I have tried flipping C11 and C14 between "wave generation" and "numerical beach" but no matter what I do, the generated waves always propagate in the increasing X-direction. I need them to travel in the -X direction.

Is this possible or all domains need to have the beach on the right side (max X) and wave generation on the left side (min X)?

Based on the attached figure, I have generated the mesh with:
control.txt:

B 1 5  
B 10 434148 434698 4702302 4704174 -8 6 (or in simpler terms: 0 550 0 1872 -10 6)
B 130 1
C 11 7
C 12 3 (assuming this will work with periodic boundaries I set at C22 1)
C 13 3 (assuming this will work with periodic boundaries I set at C22 1)
C 14 6
C 15 21   
C 16 3
C 22 1 (will need to have periodic boundaries applied to lateral boundaries so I used C22 1)
G 10 1   
G 15 2     
M 10 8
M 20 1

ctrl.txt is also attached - I have tried giving some angle to the waves with B 97 and B131 and they both generated perpendicular waves (still going in the +X direction). Then I removed

B97/B131

and used

B 105 61 434648 4704174

which gave me wave angles but still propagating in +X direction.


Thanks for all suggestions - I can provide additional information to help resolve the problem.
Cheers
