Hi this is my Rnd for waterfall with Realflow

I want to do same thing with Houdini..

I setup the scene but a have a problem whan a run the simulation particles are not collision with
waterfall geometry. Then a put hihger value in tab collsion - Volume - mode Ray intersect - division from 10 - 200
after that particle colide with surface but some of the is going true the surface…

Here is the scene. Work is done in H9.1

Thank you…

I took a look at your file to see what I could do. One thing which I suspect may have been throwing you off, is that your normals were a little messed up (some were pointing in, some were pointing out) so I fixed that. I'm not sure why you chose not to include the walls into your sim… so I also left them out.

Personally, I prefer to bring objects in as static objects, and to bring each chunk of geometry in as it's own static object. This allows you to have better control of the collision geometry if you had have had more complex and varied stones in your scene since you can tailor the collision resolution on a per-boulder basis.

I've never worked with thin-plate collisions before, so I extruded your ground plane into a volume.

I'm not sure why you chose to facet the geometry, so I've bypassed that.

Hope this helps you out, let me know if you have any problems. I'd also be very interested to see the results with your finished sim.

Thanks Allegro, i found a solution probelm was with tin plate collision, after extrude it work fine,

Happy New Year

CeeGee, how were you happy with the Houdini Fluids result vs Realflow? What about the speed?

RealFlow is very fast, Houdini fliud particls a bit slow the RF
