Helo,

I post a short animation of a liquid tank and a cube falling in it. The cube
movement was first simulated alone with MegaPOV MechSim patch. Each frame
was saved and used as an input for a fluid simulator I'm working on. After
the fluid simulation, both the liquid isosurface (in dfd format) and the
MechSim mesh are read and put together by MegaPOV for rendering.

In this animation, the water doesn't push the object, I think it is the
reason why the behavior of the liquid is not as I expected.

The video is MPEG1 encoded.

Regards,
Fidos

Yeah, it looks like that cube is one *really* heavy object. The water in
this case looks more like some glue or oil, cause I'd expect it to "splash"
more. That nice wave that covers the box is convincing, but doesn't look as
viscous (is that a word, or did I make that up :-p) as water normally is.

I've never used MegaPOV and/or MechSim, but maybe it's possible to define a
plane which, when the box intersects it and drops below, forces the nodes to
move smaller, much like a dampener? There'd be the effect of a little
interaction between liquid and box, even though waves would still have no
effect.

Altogether, this one does look great. If you think of it as oil, I'd say
perfect. :-)
