# Recent Context
## Last Updated
2026-05-28. The wiki was trimmed to finite-element scope, then solid element, shell element, MITC, dynamic buckling, and shell finite element review sources were ingested, including `.raw/SolidElement/`.
2026-05-29. The wiki is finite-element scoped and now includes `.raw/AbaqusAnalysisUserGuide2/` as the Abaqus analysis-procedure and analysis-technique thread, `.raw/AbaqusAnalysisUserGuide1/` as the Abaqus input/execution/output thread, `.raw/AFirstCourseInTheFiniteElementMethod/` as an introductory FEM textbook, `.raw/AbaqusTheoriesManual/` as an industrial FE theory reference, and the existing Bathe, solid element, shell element, MITC, dynamic buckling, and shell FE review sources.
