+
+## Definition
+
+midas FEA is a finite element analysis product from [[MIDAS Information Technology]] for advanced nonlinear and detail analysis, especially in bridge and civil structural engineering contexts.
+
+## Manual Coverage
+
+The [[Midas-FEA-Analysis-Manual|Midas FEA Analysis Manual]] organizes the product around structural elements, reinforcement embedding, interface elements, nonlinear material models, equation solvers, nonlinear iteration, linear static/dynamic/buckling analyses, construction stages, heat transfer and hydration, contact, fatigue, and CFD.
+
+## Why It Matters
+
+For this vault's custom-solver thread, midas FEA is a useful reference product because its manual exposes the analysis features and validation targets an engineering FE solver must make explicit: model input, element libraries, state-dependent materials, solver selection, convergence checks, and output quantities. [[midas Civil]] complements it with bridge-oriented member modeling, staged construction, prestress, seismic, moving-load, and civil design workflows. [[midas NFX]] complements it with a broader general-purpose structural, field, contact, fatigue, optimization, and forming-limit analysis manual.
