Initial Fill - part 1

[Jason Collins]

Hi



Could you give me some guidance on what I need to do to solve this problem please?


I cant get the container to quickly fill properly in Phoenix 2.2. The results are very wrong.

I have enclosed grabs showing the results of a container and liquid cylinder with a gap between them and another set with the two intersecting each other.

I tried both because of the following instructions, but the scene is basically the same as the Pouring Wine Tutorial.

One Chaos tutorial (Using Initial Liquid Fill with Containers) says ?Adjust the filled geometry by adding a Push modifier with a Push Value of about -0.9 cm. This will add a small amount of space between the meshes so they do not intersect?.
Another Chaos tutorial (Pouring Wine Tutorial) says to make the two meshes intersect.

Both meshes are STL checked, all their normals face outward and the Max units are both cms.

The PHXSimulator size is 45.15 (129) X 45.15 (129) X 100.1 (286) cms, the total cell number is 4.7 million and Initial Fill Up is not checked.





Thank you and kind regards.
Jason

Hey,

It looks to me like the emitter geometry is solid and is working in Surface Force mode - can you check in its right click properties if both Solid and Clear Inside are unchecked?

In Phoenix 3.0 we upgraded the liquid solver from a grid-based to a FLIP solver so the liquid particles can be traced and kept alive, preserving the volume. I have to take a look at both tutorials, but with 3.0 it's not an issue whether the emitter geometry intersects the bottle geometry or not - a source would not be allowed to create liquid particles inside a Solid geometry such as the bottle. In 2.2 however, the grid-based solver would create liquid inside the Solid geometry and in such a case you are going to have to check 'Clear Inside' in the properties of the bottle geometry.

I would strongly advise you to upgrade to the latest Phoenix 3.05 though.

Cheers!
