Abaqus User Subroutine Manual Index

This file routes AI agents to the authoritative Markdown manual spans. Search this index first, then read every source_ranges entry for the selected section in order. Do not make implementation decisions from summary alone.

Agent usage

1. Confirm that all 69 required source chunks are installed beside this file and that their combined digest matches source_sha256. Stop if files are missing or the digest differs. When a selected span contains an images/... link, also require that referenced companion asset; images are not included in the Markdown digest.
2. Search by exact symbol, section_id, product, or a keyword.
3. Read the complete record and then load every listed source span in order.
4. Use content_anchors for focused navigation, but inspect surrounding manual text for constraints and context.
5. Treat the manual spans as authoritative; the generated summary and keywords are retrieval metadata.

Example search:
