Hello,

I have a FLIP simulation, a ball moving to the fluid. I add a Sopsolver to the flip simulation. With this Sopsolver I deform the fluid with a VOPSOP.

If the Sopsolver is inactive there is impact between the sphere and the fluid particles but no deformation.
If the Sopsolver is on, there is deformation but no splashes.

How can I have the deformation and the impact ?
Is there a way to record impact of fluid particles and then turn off VOPSOP deformation only on theses particles ?

I know someone could say to make the sim and displace afterward but it doesn't solve my problem. I need deformed FLIP first.

Thanks for your help.

Maybe this is your answer :

Just put sopsolver1 before flipsolver1 in the multisolver1 !

:?

very nice ! Thanks Joker386.
I didn't notice the importance of input order withthe multisolver ops:

The thing is, the sphere doesn't push the particles away. It looks like the Flipsolver is acting on impact but is leaving the sopsolver render the simulation the timestep after …

Well I go back to dive in DOP abyss !

ok
I was using a rest sop in my sopsolver to be sure to get proper displace.
I have to find another way

Well …

I would like to use impact data form the sopsolver. But it looks like the impact particle are calculated at each frame.

How can I get accumulation of impact attribute in simulation ?

Thanks for you help

Hello,

I made a new test.
The goal is to delete some particle from a simulation and use theses deleted particle as source for another flip sim.

I can erase my particle but I don't how to add theses partciles to the other sim.

thanks for your help.
