Simulate

FVS runs in the R worker, not here. Saving a grouping fills the queue; the worker drains it; this page reads it.

  1. 1Queue status

    Each scoping group is tracked as queued, running, complete, or failed.

  2. 2Representative stands

    FVS runs against the representative stand and variant recorded for each saved group.

  3. 3Pathway Compilation

    Completed simulation trees can be compiled into the treatment sequences used by Pathways and Toggle.

  4. 4Objective calculation

    Management-objective summaries are calculated from available simulation output rather than estimated in the interface.

This page reads the project’s current FVS queue and post-processing state. Completion and period counts are shown only where the database provides them.

The status panels below are the source of truth for what can run next.

Queue

Every group has been simulated.

10 scoping groups queued for FVS

Demo: replays the Kökez run made with the FEMS worker (rFVS, SN variant) — the values are the real FVS output.

What the worker has to do

One FVS run per representative stand, per variant it has to load.

Outstanding before FVS can run

The worker will fail on each of these. They are shown in the order it reaches them.

  • Every group has treatments
    2, 4, 5, 6, 7
  • Species named in treatments mapped to FVS species
  • Regenerating treatments have a regeneration defined
  • Every group has regeneration
    3, 4, 5, 6, 7, 8
  • Regeneration species mapped to FVS species

After the run

Two passes that turn finished simulations into what the analysis modules read. Both are pure SQL and run here rather than in the worker.

Summarise simulated standsdone

Reduce the simulated trees to per-stand metrics — density, diameter, volume, cover — which the management objectives read.

Compile pathwaysdone

Walk the tree of simulated stands and name each distinct treatment sequence. These are what Toggle allocates area between.
