Products: Abaqus/Standard Abaqus/AMS
Benefits: The performance of the AMS eigensolver has been improved for large models that contain many distributing coupling constraints or other features with Lagrange multipliers (for example, contact interactions, connectors, or hybrid elements).
Description: Enhanced handling of a large number of constraints in the AMS eigensolver delivers improved performance for large-scale models with many constraints.
Table 6–2 illustrates the performance improvement in the AMS eigensolver for two industrial vehicle models. Both analyses were run on an HP Linux machine with dual 3.0 GHz Core 2 Duo processors and 16 GB of memory.
