Keyframing liquid simulation.

Hi guys, I’m having a few issues with a liquid simulation. In my animation I melt an object so I need the simulation to start about 3/4 through the entire piece. I’m wondering how you keyframe the liquid simulation to start at an exact frame?

Any help is much appreciated.

I did something like this and I used a script to pull a mesh out the fuild sim and scuplted to blend between the two. THis was doen age ago so I am tempted to do it again with all the new tools and renders. http://www.youtube.com/watch?v=iwmUo1wjfQs

See I’m after the reverse of that. Or even just being able to put the simulation on hold untill the camera gets to the right spot would be fine.
