Is it possible to get the current solve substep number inside the sop solver networks ?

regarding the DOPnet level substeps you can use $SF variable on DOP node parameters or @SimFrame in DOP level wrangle nodes to get absolute substep number

however many solver nodes (POP, Flip, Pyro, Vellum, ...) can introduce additional substeps usually through internal Gas Sub Step which can be nested, so in those cases you may need to accumulate your own counter at particular spot within the tree

Thankyou for answer tamte.
I understand that in DOP context i can use $SF or @Frameinc|@SimFrame .
But i don't understand how to get these variables exactly in SOP Solver.
That's why I'm asking here )

to get those variable values you can usually use stamp() hscript function and it seems to work for ST , however for some reason SF is giving me 0
the same if I use stamp() function with new variable in ../solver1/d/s/Stamps section based on $SF

but direct reference seems to work

Thank you very much for your answer and example. Very grateful for your help
