History:

Particles have been part of Houdini for a long time. They are now fully integrated in dops and were once a separate solver. Why mention this? To make sense of some of the now "older" posts and example files.

Tips for Particles in Dynamics and the workflow

To create a particles simulation you can either create one from shelf tool (it will create an AutoDopNetwork  (a dopnetwork node) with a default setup having gravity, attributes set to "Add to inherited velocity" and Variance set to 1. You can also create a popnet inside of sops by hitting tab and typing popnet (just a dopnet node inside of sops).

In the shelf tool setup, you also have a geo node that contains the particles. You can do the same thing in sops by using a dop import node, or using the convenient object merge tab on the dopnet node to bring out just your particles by typing popobject in place of the * that is in the Object field.

There are many pop nodes - hit tab and type pop to see the variety.

A few that I want to point out are:

In addition, you can manipulate your pops with vex.
