# Midas NFX Analysis Workflow
|
|
|
|
## Definition
|
|
|
|
The NFX workflow is the production analysis loop described in the [[Midas-NFX-Analysis-Manual|Midas NFX Analysis Manual]]: define the finite element model, define the analysis case, solve, and inspect postprocessing results.
|
|
|
|
## Model Contract
|
|
|
|
The manual frames model definition around nodes, elements, mesh, loads, boundary conditions, analysis type, and result interpretation. It also makes the coordinate-system contract explicit: global coordinate systems, nodal displacement coordinate systems, element coordinate systems, material coordinate systems, element result coordinate systems, and element formulation coordinate systems can all be distinct.
|
|
|
|
## File Contract
|
|
|
|
The source identifies model files, solver input, run logs, text output, and binary postprocessing data. For a custom solver, that split is important because test harnesses need stable locations for model input, execution records, raw result files, and postprocessed quantities.
|
|
|
|
## Analysis Families
|
|
|
|
NFX covers linear static structural analysis, normal modes, linear buckling, direct/modal transient response, direct/modal frequency response, response spectrum, random response, nonlinear steady/transient heat transfer, nonlinear static, nonlinear quasi-static, nonlinear explicit transient, and nonlinear implicit transient analysis.
|
|
|
|
## Solver Development Use
|
|
|
|
This page is a requirements checklist for the outer application layer of a solver. Before implementing an element or constitutive model, the solver needs a concrete model schema, unit convention, coordinate-system policy, analysis-case type, input/output file contract, result-coordinate policy, and postprocessing result list.

## Connections
|
|
|
|
- [[Finite Element Program Implementation]] gives the generic implementation data flow.
|
|
- [[Midas FEA Analysis Workflow]] and [[Midas Civil Numerical Analysis Model]] are sibling MIDAS workflow references.
|
|
- [[Finite Element Modeling and Convergence Checks]] connects the workflow to model idealization and verification.
