Troubleshooting

"No FLIP Solver found" / "No FLIP Object found" — three causes. Discovery looks at the dopnet's direct children, so a solver inside a DOP subnet is missed. Or it is a SOP FLIP setup (see below). Or the path points somewhere unexpected.

I use the SOP FLIP nodes — not supported directly. What works: leave DOP Network empty and add Add Linked SOPs rows for your flipcontainer and flipsolver SOPs, which carry particlesep and gridscale under those names. They hold those values independently, so you need a row for each. Substeps, CFL and the bounding box cannot be driven this way.

Connect took over an expression I wrote — by design, and it said so in the report. Untick that parameter's Link checkbox to leave it alone. Unlink is the conservative direction and would have left yours alone.
