after retiming a ripple sim , the result flickers a bit.
you can run a mplay to see the problem. it's subtle but there.
finnally the sim will be rendered as water,so that problem might be very obvious.
i didn't expect so far a flickering in a mesh not changing topology. it's more or less like the flickering when doing pyro retime.
please download the attachment and have a look, that may help me out. it confused me a lot.
THANK YOU GUYS.

The simple solution is don't retime your sim. Typically a retime more than +/-50% in either direction is going to produce an anomaly. Try dropping your FPS down from 24 to 6. Then increase your end frame to 2400. Render that out, and play it back at 24fps to achieve your 0.25 retime value.

This doesn't seem to be a problem caused by retime node.
Check it again you'll find there is some deformation probelm on your REST geo, for example frame 30,
you got "slump effect" on the surface.
So I tried to smooth it out by adding a attribblur node, then the flickering disappeared.
