# Abaqus Analysis Procedures
|
|
|
|
## Definition
|
|
|
|
Abaqus analysis procedures are the high-level solution workflows that define which finite element equations are solved, how they are incremented, and which solver strategy is used for static, dynamic, stability, coupled-field, and special-purpose analyses.
|
|
|
|
## How It Works
|
|
|
|
For nonlinear equilibrium, ABAQUS/Standard generally solves residual equations with Newton iteration. Each increment linearizes the equations about the current state, solves a tangent system for a correction, updates the solution, and checks force residuals and correction sizes for convergence.
|
|
|
|
The manual also covers modified and quasi-Newton strategies, automatic time or load incrementation, cutbacks when convergence fails, and specialized procedures such as Riks-type postbuckling, direct and modal dynamics, harmonic response, heat transfer, diffusion, pore pressure, coupled fluid-solid response, piezoelectric response, substructuring, submodeling, fracture mechanics, and design sensitivity analysis.
|
|
|
|
The user guide adds the execution-facing side of procedure choice: procedure keywords appear inside analysis steps, are checked by syntax or data-check runs, and determine which output, restart, and resource patterns matter for the job.
|
|
|
|
Volume II of the user guide expands the procedure catalog in detail: static, buckling, postbuckling, quasi-static, cyclic and fatigue, implicit and explicit dynamics, steady-state dynamics, modal procedures, heat transfer, thermal-stress, fluid, electromagnetic, pore-fluid, mass diffusion, acoustic, Aqua, and annealing procedures. It also distinguishes general steps from linear perturbation steps.
|
|
|
|
## Why It Matters
|
|
|
|
The procedure determines the mathematical problem more strongly than the element mesh alone. A shell or solid model can behave very differently under static equilibrium, implicit dynamics, explicit dynamics, eigenvalue extraction, postbuckling path following, or coupled thermal-stress analysis.
|
|
|
|
