Experts in Tolerance Analysis Share Their Insight Into Handling Tough Tolerance Analysis Scenarios
Not every model is three pieces of sheet metal and a simple set of bolts. Some models pose a greater challenge than others, and these presenters and workshops combined to help users tackle those challenges.

Effects of Dimensional Variations of Suspension Components on Vehicle Dynamics
Working With Large Models - Black Box Methodology
- A big model with a lot of MTMs and a big stackup can be replaced by some points and tolerances;
- Only final results can be shared with other companies. Modeling strategy and process tolerances are hidden;
- Several Black Box Scenarios can be done based on only one model Data Generator Model run;
- Heavy FEA Compliant models can be replaced by a few points (also optimizing FEA licenses).
- Depending on the result some curve fit must be done and some errors are generated;
- Some local datums must be created to measure the specific relationship between features;
- The original model is split, it’s necessary to manage two models;
- Some tricky higher order interaction, if not detected, can be lost;
- On the black box model, the sensitivity doesn't show the contributors (they are all bundled).
