FLIP IN EGG - LEAK ISSUE

[newbee]

I am trying to do this sim, where i have an egg with some flip inside

but the flip inside the egg seems to leak as the egg moves forward

 

these are some key things i am doing

 

1.I do a voronoi and fracture the egg, i do the fracture sim separate from the flip sim.

   in the flip sim i used the fractured egg as a static object with deforming geometry to collide with FLIP

2 i tried increasing the UNIFORM DIVISIONS

3.i tried increasing the  COLLISION OFFSET

4.i tried REVERSING THE NORMALS OF THE EGG

5.i tried increasing the COLLISION PADDING

6.i used a TRAIL SOP to calculate the velocity of the egg

7.finally i set the FLIP SOLVER > VOLUME MOTION >

  COLLISION > VELOCITY TYPE TO POINT INSTEAD OF RIGID

 

 

is there something that i am forgetting?

why does the flip leak out of the egg??

 

i have a scene file attatched

u can see the leaking effect on the third or fourth frame

so u can just step through the first few frames to see the issue

I messed around with it a bit and cheated slightly. ended up matching velocities and using glue contraints on the fractured egg. used one dopnet to simulate as well. take a look. if your egg is only going in one direction this is a way to cheat it. you flip velocity from collisions was set to 2x before.
