Particles and fractures

[Omy]

Hi,

Im a newbie to Houdini. I want to know how can the interaction between particles and fractures can happen(Eg: suppose if a particle hits the rigid body object say sphere(sphere is a rbd object),the sphere should fall off.)

Can any one explain me with an example

Sincerely,

You can see how the debris tool is integrated with the RBD solver from the shelf.

Create a fractured or glue object then use the Debris tool from the Particle Shelf on the fractured RBD objects.

In DOPs you now have your particles interacting with the RBD pieces. If you increase pscale on the points and/or increase the mass, they will have more weight.

Make the relationship mutual and you will have particles pushing rbd pieces.

You can also work up an example from scratch but again you need a Particle Object and Particle Solver in your DOP network and with a mutual collide relationship (Merge DOP or Collide Relationship DOP).

Again set the pscale and density or as an alternative set mass to add enough mass to your particles to kick the RBD pieces around.

You can create nice exploding spheres this way. See attached file.

It is easy to add a LOT of particles and with a lot of mass, your RBD pieces may be flung thousands of units away...
