Question about flip and thin collision mesh

[ibaniser]

I am trying to simulate egg whites inside the eggshell which then gets pushed out by an escaping yolk (the yolk is not a fluid, just a deforming collision object), and drips down onto the eggshell.

I can get a simulation running by making the eggshell collision geometry really thick prior to vdb conversion, however the fluid actually needs to conform to eggshell surface which is really thin, so this is not going to work.

But without some thickness the fluid simply exits the collision geometry. What is the best way to approach this?

Cheers

Create a thick shell for collision but only render the thin shell.
