Combining Solvers With a Multi-Solver 

A cool thing that you can do in Houdini is to stack solvers with the help of a multi-solver. In this tutorial I'm showing a simple example of this by using a pop solver together with a bullet solver.

    doesn't work on houdin 16 apprentice !

      pop curve force do nothing ???

    Really? Sounds, strange? As you can see I'm using 16 in the video.

    It works fine for me. (houdini Apprentice 16)
    Nice tutorial Mikael, thank you! :)

      Great! Happy to hear :)

    I have the same problem as Grego, unfortunately. Popcurveforce does nothing, once it's been added and the correct path chosen. Vers. 16.0.633

      It sounds strange. If you upload your scene somewhere, I'll have a look

    When you follow this tutorial, the bullet solver gives you a warning about the name attribute, should I try to fix it?

      It doesn't really matter, but you can put a pop wrangle under the pop source and type "s@name=sprintf("name_%d",i@id);" to make it go away :)

    Thank you for the tutorial! Works well, however I tried to do similar simulation with FEM(non packed) with intent of having spheres follow circle, bouncing into one another or for example a whirlpool of papers(cloth). While everything simulated, the geometry got extremely distorted along the circle. Can you please advise what I might be overlooking.
