Monte Carlo Simulation

Run thousands of virtual builds to see the true distribution of your assembly outcome. The engine respects bilateral tolerances, loop direction, and sigma capability to report mean, σ, mean ± 3σ, observed min/max, and predicted yield vs. your spec—fully reproducible via seed and adjustable sample size. Unlike RSS (which assumes linearity and symmetric, normal tolerances), Monte Carlo propagates your actual distributions and non-linear interactions, exposing tail risk and real pass/fail probability.

Analysis Summary

Create a polished, audit-ready PDF in one click. Each report captures project headers (title, analyst, date), objective, conclusions/recommendations, and full traceability (report ID, app version, seed, sample count, spec settings). It documents inputs (loop direction, nominal, bilateral/asymmetric tolerances, sigma level) and outputs (mean, σ, mean ± 3σ, observed min/max, predicted yield), with pass/fail summaries plus results and input tables. Share a clear, reproducible record stakeholders can trust.
