Eigensolver and linear-solver options (solver) keyword reference¶

Auto-generated

This page was generated from the ACE3P source tree by tools/extract_keywords.py on 2026-10-20 (source revision v2026.10 2026-10-20). Keyword names, types, and defaults are taken directly from the code. Descriptions live in the module user guides and the command syntax pages. Do not edit this file by hand.

86 keywords found. Sections are the block named in a dotted key (EigenSolver.Tolerance) or, for bare keys, the name of the container variable the code reads them from (domainkvc becomes Domain). A blank Default means the code reads the keyword with find() and the fallback is not a literal, or the keyword is a block or switch. Presence required means the code aborts when the key is absent.
