Since simulation nodes is now available in the official builds(beta/daily builds), I will start putting the files here. Most of these will also be up on gumroad/ko-fi, mostly for free at a later date.
!! Note that you will need at least Blender 3.6 to be able to run these files.
For this one you can set the number of data columns/value min/max in the geometry nodes modifier panel, though you will need to reset the simulation for the changes to take effect(rewind back to frame 0).
