Anatomy of a smoke solver: Like a compressed version of the above video, in russian (but with good subtitles), and assumes even less knowledge about houdini.

Fluids masterclass: Another good one, showing you how to build a smoke solver from scratch, good overview of how both particle and voxel solvers work.

Perfect intro if you've learned sops/vops/vex first, and feel the need to dive into pop dops (I realise I'm one of the few to learn Houdini this way, seems everyone else goes into particles first.)

Pops masterclass: Excellent 90 minute into to pops (particles).

Richard Lord RBD experiments: He's done some amazing deep dives into rigid body dynamics, with a focus on little autonomous critters and constraints that get created during a sim, really cool stuff.

A great feature of this tut is that it presents a 'houdini-think' way of working if you can get your head into this state, the rest of Houdini flows much easier. Very nicely paced tutorial that is a good intro to Houdini itself, as well as dops.

Melt an angel: If you're just starting out, watch this.

These are definitely not 2 hour masterclass lectures! Some text rambles on, some is super brief, but the idea is that they show the technique and the minimum nodes required to setup an effect. These examples are mainly about creating simple self-contained setups, with as little roundabout references as possible, with the shortest explanation possible (but no shorter). They might be easy to create, but they're not easy to pull apart, and even harder to understand when they don't work as expected. Ironically, a lot of the initial confusion stems from the way DOP networks are created by the 'user friendly' shelf tools. There's still some stuff that I think is badly laid out and overly complicated, but I'm now able to setup my own particle/pyro/rbd sims without annoying my co-workers too much. Having chipped away at it for a few months, I can say it's not that bad. Parameter panels look different, data flow is no longer linear, the geometry spreadsheet has gone weird, even the base layout of nodes is slightly different, nothing can be laid out in straight lines anymore, almost like its intentionally throwing you off balance.

Just when you think you have a handle on Houdini with SOPs, enter DOPs.
