I’m currently testing PhoenixFD (for Maya, nightly builds), and really liking it so far, but I cannot seem to get rid of the stepping artifacts as visible in this image. At this point all that’s happening is an initial fill-up and some time settling. I’m using the FLIP solver (have tried others too…

can you share more details, or directly send the scene to the support? before sending the scene, one question - what is the surface level value of the mesher? if you are starting from old viscous scene, i suppose it may be 0.1, that is totally incompatible with the flip solver results. flip export…

Surface level is 0.5, but thanks for checking. Assume I should send the scene to support@chaosgroup.com ?

yes, this is the mail very strange, i was ready to bet that the surface level is to blame, the flip itself does not produce step artifacts, because it’s particle based, but the result is converted into grid format to make it renderable by the old pipeline based on a grid mesher, there are no visi…

I’ve sent the scene through. I was originally dealing with the artifacts by using some overall displacement to hide it, but this was starting to make smaller details look wrong. I thought it was perhaps an issue with grid resolution or SPF, but these don’t seem to make much difference to the issue?

Check grid rotation. I remember had smth like this with rotated grid.

[image] VrayMultiSubTex should be able to use User Defined Properties Check grid rotation. I remember had smth like this with rotated grid. Not rotated, but translations are non-zero… I’ll try zero-ing them just in case. Setting the Conservation Method to Symmetric rather than Smooth seems to…

the flip solver is not using this option (conservation method). are you sure this is a flip? can you post an image with the info panel, i.e. where the content of ta currently loaded cache is shown (particle count, channels etc)

hm, there is not enough info in maya version, ok can you send me the phoenix log file?
