Nipactivity Catia

| Scenario | Standard CATIA GSA | NipActivity | | :--- | :--- | :--- | | | Fails due to instability | Dedicated algorithms for bead seating | | Rubber Compression (10-90% strain) | Linear solution diverges | Converges using hyperelastic solvers | | Roller Nip (Printing/Pressing) | Cannot simulate moving contact | Can simulate roller rotation vs. sheet | | Seal Compression (O-rings) | Requires complex multipoint constraints | Native hyperelastic contact |
