water destruction

I am trying to do a flood destroying a bridge. Does any have any ideas on how to have liquid break bridge with out hand keying the geo. I saw something using pflow but I am missing a step.

Hello,

You can make Pflow particles based on the Liquid in the simulator and then you could probably use those particles to drive the destruction.
I have attached a sample file how to make the Pflow particles from the Liquid - mind that this workflow is not really mature. We have a lot more work to do in making the Pflow integration better and easier to work with.
