I'm trying to get a POP network to work inside a Solver node, however it doesn't seem to accept the previous frame input. First frame works OK, but on second frame nothing happens. If I substitute the POP Network for a Scatter node instead, it works OK, and each frame the scatter generates points on the previous frame input. I'd assume POP would do the same but it does not.

My goal is for the POP object to create points to copy some geo to, and then feedback that into the POP object for the next frame. So each frame, the POP source has an ever growing geo source. Pretty standard Solver type stuff.

This may be the totally wrong way to go about this however, I am still pretty new around here. I probably don't fully understand what putting a DOP network inside a Solver is doing.

Any help/guidance/advice much appreciated!

Yeah, dop networks can't be nested like that. However, a sop solver can be wired into a pop solver.

The solver sop is just a simplified way of creating a dop network with a sop solver inside, so putting a solver inside of that doesn't make sense.
