Modus Lab builds small, sharp software for mechanical and precision engineering. The kind of analysis you can defend in a design review, without the weight of a full CAD suite.
Flatness, runout, position and the rest feed the math directly, not as an afterthought bolted on later.
Worst-case, RSS and Monte Carlo agree with each other, because the models are built to be consistent.
Every result ends with one plain-English recommendation: which feature to tighten, and what it buys you.
Tolerance stack-up analysis. Axial, radial and angular chains with GD&T as a first-class input, RSS and Monte Carlo, and a recommendation for which component to tighten first.
Open StackSenseISO 286 limits and fits selector. Pick a clearance, transition or interference fit and get the exact shaft and hole tolerances, plus the resulting play.
In buildHeat-exchanger and refrigeration-cycle calculators with real fluid properties, sized for quick design-review checks rather than full simulation.
