Simon Verstraete shared an in-depth tutorial on using improved Fluid nodes in the recently-released version of Houdini.
In this video, Simon spoke about the SOP FLIP nodes and their features, showed how to set up basic simulations, and demonstrated multiple example projects made with this set of nodes. In each example, you will see the same node being used but with different settings and ideas behind them.
And here are some of the artist's earlier tutorials:
