For days I am trying to get some slight wave motion on top of my Grid, but without any success. The basic setup is a cube, that is constantly emitting into one direction and the water is getting killed by a kVolume. Doing so the water as a constant water height and some movement.

When meshing (not using any Displacement) with the mesh set to From Particles, one can see a wave pattern on the surface.

My problem is, this pattern will stay the same for the whole animation. It doesn't look like water at all but like a plane with static displacement being pushed from right to left.

I tried a lot of stuff in order to get some movement in there:

- Animating the emitter's speed
- Adding an irrgular ground
- adding some objects inside the grid to create some currants.
- adding noise

...all this gives me nothing, just no movement on the top of the surface.

Just look in the videos, there you can maybe see what I mean (Poor Quality, but it illustrates the problem).

Do you have any idea wht I could do in order to get some movement on the top?

I'm having the same issue here on OS X, but it's only a preview thing and not related to the simulation, because when I scrub the timeline I can see the animated displacement. Sometimes it works, sometimes not, but I couldn't find a pattern so far. As a workaround I use the Export Central preview function (PREVIEW > Image sequence (*) ). This preview method is working for me.

If that is the case I am going to eat my desk because of all the time I've wasted with this one.
Danke!

Florian you are not using displacement, are you? From the videos it seems to me that you are actually using a displacement, and the displacement is not animated. That might be an explanation but you said you are not doing it this way.

Can we have a look at the scene, please? Thank you.
