Hi ! I’m playing with the fluid simulator in Blender 2.40 alpha1:
I have encountered two issues:
1 - I wanted to simulate water poured in a glass.
I have used a cylinder for the glass, with the upper side opended by removing the vertex at the center.
Normals are recalculated outside (tried too with normals inside).
I have put it in the domain object and set as an obstacle.
The water is stopped by the upper side, even if there is no upper side!
The bound box seems to be used for the obstacle instead of the real shape.
2 - I have made a trial with 2 planes (and with other objects too) with a hole, used as obstacle, to see the travel of the liquid…
The two planes are one obove the other, and set as obstacles.
The fluid ignores the first obstacle, and pass through it like there was no obstacle.
The second obstacle stops the liquid.
I have tried with 3 objects: this time, only the first and the third objects are detected as obstacles… the fluid passes through the second one!
