Driving Flip SIM using ocean source

[trishit]

Hello ,

I am a beginner with houdini ,and was trying to sim a flowing river .

My process was at sop level i made the river geo and constructed a ocean source after fixing the ocean spectrum,Then i created a dop network and inside called the ocean source at flip object and simulated the flipsolver.Now the issue is that how i see the ocean spectrum driving the ocean source ,it doesnot drive the flip particles in same manner..(i have used popadvect volume and called in the velocity of the ocean source),in the first few frames it does look like the flip is moving forward but after some time it just dies off.I am confused as is it happening because of the terrain collision or is my pop advect volume not working properly.
To avoid using the pop advect volume i also took out the velocity information from the ocean evaluate node and used it as a source volume on the volume velocity in my flip solver but this also gives me the same result.

I have attached a small file somewhat similar to what i am doing.Can u guys please help me understand this issue.


Also with this i was wodering that if i wanted to generate whitewater ,then how do i do it.I do undeerstand that the whitewater source calls DOP IO node,but in my case there is no such node as i manually created the flip solver inside my dopnet so when i select my flip fluid and click on whitewater it gives me an error saying it needs a flip object.
I am unable to understand in this case how do i create whitewater.
