N. Akinci, M. Ihmsen, G. Akinci, B. Solenthaler, M. Teschner: Versatile Rigid-Fluid Coupling for Incompressible SPH
We propose a momentum-conserving two-way coupling method
of SPH fluids and arbitrary rigid objects based on hydrodynamic
forces. Our approach samples the surface of rigid bodies with
boundary particles that interact with the fluid, preventing deficiency
issues and both spatial and temporal discontinuities. The problem
of inhomogeneous boundary sampling is addressed by considering
the relative contribution of a boundary particle to a physical quantity. This facilitates not only the initialization process but also allows the simulation of multiple dynamic objects. Thin structures
consisting of only one layer or one line of boundary particles, and
also non-manifold geometries can be handled without any additional treatment. We have integrated our approach into WCSPH
and PCISPH, and demonstrate its stability and flexibility with several scenarios including multiphase flow.

its ingredible what 3d modeling can make!
I feel like my laptop is going to explode due to the particles overload That must be a powerful computer of yours
COOL
Is this formulation valid for industrial use? Does it have proper mathematics behind it? Because I saw that frigate, how accurately does it depict real life flow?

This is not valid for any industrial use, and it depicts real life very poorly. This methods are used mostly for CGI and the VFX industry. You should be looking at other software for what you want

@@diogoferreira6589 The main advantage of something like this is performance. Its thousands of times faster than a 100% realistic simulation while still producing at least photo realistic effects. Smaller scale versions can run in real time, and the effect can be used in video games and movies to great effect.

It is, it is used for high deformation models, star collisions, some particle modelling for the aggro industry. The model is called sph, there is not too much info about it online. It does have proper mathematics, it uses the lagrangian form of navier stokes equations.

i can do these in realtime in Nvidia Flex :3 .. at any rate i would love to do these in blender

do you even know what Nvidia Flex is .. its exactly like this running in real time and the results are very accurate .. in blender i could utilize this in very interesting ways and make some interesting exparaments ... i just wish i knew where the plug in was found

it takes 6 seconds to compute a frame, most games like that are 60 frames a second, it would take 6 minutes to generate one second.

Using a ball to show the interaction with fluid as density increases is not that interesting... Try to replace it with a cube :)
