# Midas FEA Analysis Workflow

## Definition

Midas FEA analysis workflow is the production analysis sequence implied by the [[Midas-FEA-Analysis-Manual|Midas FEA Analysis Manual]]: choose element and material models, define loads and constraints, select a linear or nonlinear procedure, solve with appropriate equation and iteration algorithms, then interpret field and result outputs.

## How It Works

The manual divides the solver into libraries and procedures. Element and material libraries define the local finite element behavior. General algorithms handle loads, boundaries, equation solution, and nonlinear iteration. Analysis chapters then package those pieces into static, dynamic, buckling, staged, thermal, contact, fatigue, and CFD workflows.

This organization is useful for requirements design. A solver feature is not only an equation; it also needs input data, element data, state variables, solver controls, convergence tests, output quantities, and validation cases.

## Implementation Signals

- Element support must include degrees of freedom, coordinate systems, interpolation, numerical integration, and local-to-global assembly.
- Material support must define stress update, tangent behavior, history variables, and failure or cracking outputs.
- Solver support must distinguish direct and iterative equation solution, symmetric and nonsymmetric stiffness, nonlinear tangent update strategy, and convergence norms.
- Analysis support must define what state is carried between increments, stages, or coupled field transfers.
- Result support must expose nodal displacements, reactions, element forces, stresses, contact forces, temperatures, fatigue damage, or aerodynamic coefficients depending on procedure.
