Transition to First Frame of Fluid Sim I'm trying to do a "melting object" effect using fluid simulation (in 2.77a), but I'm having trouble doing a smooth transition.  My brute-force approach is to use keyframes to turn the visibility of the original object &amp; fluid off and on (respectively).  The trouble is, the first frame of the fluid has flowed more than it should have, compared to subsequent frames, so the transition from object to fluid is very abrupt.
I double-checked that the simulation start time is 0, and played around with the settings.  The only thing that helps is increasing the resolution, but I'm already up to what my computer can reasonably do.

Has anyone else seen this?  Any tricks for getting around it?  I checked various fluid tutorials, but I didn't see this problem covered.
Thanks.

[Updates]
Below are frames 23-25 (24 is the first frame of the simulation).  Note that 24 has already "melted" quite a bit, but there's almost no difference in 25.  The file is currently available at http://www.pasteall.org/blend/42419.
Thanks to @Jbergman for the answer (see comments for additional details).

The main problem was that I had a concave "saucer" obstacle under the fluid, hoping that it would keep the fluid from pooling against the sides of the domain.  The fluid wasn't technically touching the saucer mesh, but I had the saucer's Volume Initialization set to Volume.  This caused the simulator to include the concave volume in the obstacle.  Setting it to Shell fixed it (using a closed mesh as the obstacle may have fixed it also, but I didn't try this).  [Since the saucer was invisible, no one could have found the problem without the original blend file; sorry about that.]

A few other points that he reminded me of:


The domain was much bigger than it needed to be.  Making it smaller
allowed me to use a higher resolution.
I didn't apply the scale to the domain; apparently this can cause
other odd behavior.
The resolution is going to limit how close the first frame looks to
the original mesh.  It's close enough now that I can just copy the
first frame of the domain mesh and use it for the first 24 animation
frames, instead of the original mesh.  If I was really ambitious, I
think could edit this domain copy to look more like the original and
use shape keys for a smooth pre-sim transition, as discussed in the
comments.


Below is how the first frame looks now:
