mesh artifacts

[helmisvfx]

hello

after simulating about 100 frames mesh artifacts appears like small noise spikes on the surface so splashes are created all over the place
is this a step/frame issue?
this is a ship on the ocean project.

thanks

can you post an image?
we just have fixed a similar issue, that was actually caused by hovering particles over the surface , but it's not sure what is it in your case.

artifacts


i have 2 problems , the artifacts and at the start i have this line with splashes, which it might be by the fact that the grid is linked to the ship..

thanks

the artifacts are spf related, the common solution is to increase it.
about the line - usually the very first frames are not rendered, because the boat wake, the waves and etc are not evolved to stable state and the line is not a problem. if you see in our ship sample the rendering starts from frame 250.
but if you need to prevent the splash birth, increase the threshold, this is the only way.
btw, both the problems are not present in the flip solver, you can ask the support for nightly access.
i made a fast test with the very same scene and both the solvers to illustrate my words, see the attachment

Thanks a lot Ivaylo, i downloaded the last n.built and will give it a try
cheers
