Interactive engineering calculation and visualization tools.

TOOLS
01 — STRESS ANALYSIS

Interactive 2D Plane Stress / Mohr Circle

Interactive visualization of two-dimensional plane-stress transformation, Mohr circle, hydrostatic/deviatoric decomposition, and Tresca/von Mises representations.

Open tool
02 — FASTENERS

Bolt Pretension / External Load

Interactive visualization of a preloaded bolted joint under external tensile load, including bolt and joint stiffness, preload, load sharing, and joint separation.

Open tool
03 — TOLERANCING

Monte Carlo Tolerance Calculation

Interactive tolerance-stack simulation for a Part 1 + Part 2 assembly — Normal or Linear distributions, a shared manufacturing process capability, and a randomized pairing simulation compared against Worst-case and RSS-predicted spread.

Open tool
04 — STATICS

Rigid Body Reaction Force Solver

Reaction forces for a rigid body under arbitrary applied forces, moments, and equivalent static inertia loads — xyz, single-, double-, or triple-direction reactions, with a built-in equilibrium crosscheck.
