6.4 Removal of parallel Lanczos and Lanczos restart features

Product: Abaqus/Standard  

Benefits: The Lanczos eigensolver can no longer be run in parallel over multiple frequency ranges. The Lanczos restart feature has been removed.

Description: The direct solver used within the Lanczos procedure can run on multiple processors. However, the Lanczos eigensolver no longer runs in parallel by division of the frequency range of interest.

The Lanczos restart feature is no longer supported. When restarting an analysis, all eigenvalues requested in a Lanczos step will be calculated even if they have already been extracted in a previous Lanczos step.
