Short(-ish) tutorial on how to build a very simple smoke solver from scratch, using bottom level nodes in Houdini. Had to keep it under 500mb so unfortunately it's a bit compressed.

Feedback appreciated, especially on if there was too much / too little information etc.

    Thanks a lot, super useful overview!

    Very interesting but i didn't get it to work, there seems to be simulating something but I get no visual output, is it possible to give a .hip so I can compare?

    Finally got it to work! removed all the switch nodes, there seemed to be something not working with the path 'opinputpath("../.", 0)' in srcField so I linked directly to the volume sop. I love these simple setups as a starting point for experimenting. Thanks!

      Glad you got it to work! I just used the switch nodes to switch between the particle and the volume source. All switches have to be linked. e.g. if you are feeding the single particle into the DOP network, then you also have to use the SOP Geometry and GasParticleToField nodes. (instead of SOP Scalar Field and GasCalculate)
