Hi, I’m busy doing some tests for a shot i need to do. I’m using a sphere object for the test now, but will be a character coming out the water. Issue iIm having is that fluid cells are being created inside the object, but only on the polygons where the normals are facing downwards. I’ve attached …

i’m not sure what you are trying to do, but first be sure that you interpret the preview correctly. don’t forget that by default the preview is set to show the cells with intermediate liquid values. i recommend you to increase the upper preview value above 1 to be sure what is happening or to render…

All I’m trying to do is have the sphere come up out of the water. The Character i’m going to be using is very complex so having these issues with just a sphere is a bit annoying, everything else is working perfectly it’s just this little issue. Attached is a render I did the other day as a test. No…

you mean the fact that some cells remain wet and continue to produce splash? this is very common annoying effect when dealing with curved objects, usually helps to blow away the liquid turning the object for a moment into weak air source. this is the worse back draw of the grid solvers that the ob…

Ah ok thanks so much. How would you recommend briefly blowing those cells away? So sorry for all the questions and I really appreciate all your help :slight_smile:

Hi, I tried to reproduce your problem, but I was unable to get the same behavior. Can you send a scene to phoenix@chaosgroup.com Thanks

You can try unchecking the “Clear inside” in the Phoenix FD properties of the Sphere, but that will only work for the underwater part.

clear inside is for some special cases, for example when you push the liquid by a wall, and the wall must leave dry space behind itself

hmm, I did that with my sim I tried last night as it started to look promising, however it seemed to fill up the inside of the sphere as the animation went on. See attached. Did it work your side after the sphere was out of the water? How far did you manage to sim up to? I’ll test this again tonig…

yep, but I got it working with a negative source :slight_smile: What I did is, I created new Source with discharge: -10, and temperature: 300 and added the Sphere as emitter. In the Phoenix FD properties of the Sphere, make sure that the “Solid object” and “Clear inside” are checked. You can take…
