The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Elastica++ combines performance-oriented kernels with shared-memory parallelism to sustain teraflop-scale throughput despite complex discretization domains and physical interactions.

C2weakest assumption

The Cosserat rod model plus the chosen contact and multiphysics coupling schemes remain sufficiently accurate for the demonstrated biophysical regimes without requiring additional validation or model extensions.

C3one line summary

Elastica++ is an open-source high-performance framework implementing the Cosserat rod model for large-scale multiphysics simulations of slender elastic structures.
