Ocean Simulation Wave Resonance Problem

[jstrob]

I just installed latest nightly and without any particle, on this beach wave lapping test, I get huge wave created on the border (and yes my borders are all opened). Do you think you can fix this quick? Increasing spf will double and triple simulation time just to remove those unwanted waves when the rest of the sim could be ok with 1 spf...

Later in the sim those unwanted waves seems to be crating lots of turbulence and destroy the look of the wave.

Hey Strob,

Can you give us more info on that setup or the scene itself?

Thanks!

Hy Svetlin!

It's basically the beach scene example. I just reduce the size of the box. spf is set to 1. I changed some settings to tweak the foam and size of the waves but on this example I deactivated all particles and those side unwanted waves are always there no matter the settings except spf. If I set spf to 5 they become less noticable. But anyway I think I will need higher sfp cause it stabilizes everything which I think I will need to get the result I want. But sometimes it could be nice to not have them and silmulate at 1 spf.

I wonder if unchecking motion inertia could help (the box itself is not moving).

thank you.

Unckecking inertia doesn't help:

I think this is a known issue where the wave force may reflect from open walls, but it's just a guess. In case it's so, it would happen with older builds too. You could reduce that effect if the ocean tex is aligned with the simulator too.

I've been trying to find time to rework the wave force completely, but still can't get there. Can you verify that an older build still does show the same effect?

[jstrob]

I will try with an older build when I find some time. But when I look at the tutorial on the beach scene i don't see that effect in the example and the spf is set to 1 if I remember correctly.
