V&V & Numerical Accuracy Simulators

Automatically calculate Richardson extrapolation and GCI (Grid Convergence Index). Auto-generate convergence diagnostic report.

Generate output distribution and tornado sensitivity diagram via GUM analytical method and Monte Carlo (up to 100k samples).

Log-log plot of truncation error for 4 finite difference schemes. Visualize the crossing point with round-off error (optimal h).

Compare central differencing, upwind, and QUICK schemes. Visualize the relationship between Peclet number, numerical oscillation, and numerical diffusion.

Calculate allowable load from fillet weld throat thickness and weld length. Evaluate weld strength under tensile, shear, and combined loading conditions.

Calculate CFD mesh quality indices such as aspect ratio, skewness, and Jacobian ratio. Identify problematic cells by comparing against acceptance criteria.

Calculate centerline and control limits (UCL/LCL) for X-bar and R control charts. Supports quality management in conjunction with process capability indices.

Calculate main effects, interactions, and ANOVA for two-level factorial experiments. Analyze experimental data using Yates method and regression models.

Calculate qualitative analysis, minimal cut sets, and system failure probability for fault trees with AND and OR gates. Useful in reliability design.

Calculate RPN (Risk Priority Number) from Severity (S), Occurrence (O), and Detection (D) in Failure Mode and Effects Analysis. Identify priority improvement items.

Calculate process capability indices Cp, Cpk, Pp, and Ppk. Real-time visualization of defect rate and sigma level from specification limits and process distribution.

Calculate reliability of series, parallel, and k-out-of-n systems. Derive system reliability function and MTTF from component reliabilities.

Bidirectionally calculate sigma level, DPMO (Defects Per Million Opportunities), and defect rate for a process. Supports setting Six Sigma improvement targets.
