Running simulations

Before you run​

Make sure you have:

  • At least one assumption configured
  • At least one output configured
  • A rep count set in the Reps field (default: 1000)

Starting a run​

  1. Set the rep count in the sidebar (1–10,000).
  2. Click Run in the header.

The workbook file is uploaded to the server along with your config. A simulation job is created and runs asynchronously.

Progress indicator​

A progress bar appears while the simulation runs. Microstat polls the job status every second. Large rep counts (5,000–10,000) may take several seconds.

What happens server-side​

For each iteration:

  1. The workbook is loaded into the simulation engine.
  2. Each assumption cell is overwritten with a sampled value.
  3. The workbook recalculates.
  4. Output cell values are recorded.

After all iterations complete, results are returned and visualized.

tip

Use 1,000 reps for quick exploration. Use 5,000–10,000 for stable statistics when presenting results.

Rep count limit​

The maximum rep count is 10,000 per run. This limit is enforced server-side.
