# midas NFX

## Definition

midas NFX is a general-purpose finite element analysis product from [[MIDAS Information Technology]]. The [[Midas-NFX-Analysis-Manual|Midas NFX Analysis Manual]] presents it as a structural and field-analysis program covering linear, nonlinear, dynamic, heat-transfer, fatigue, contact, and optimization workflows.

## Manual Coverage

The manual organizes NFX around model definition, node/DOF and coordinate-system conventions, element libraries, material laws, equation solvers, eigen extraction, linear and nonlinear dynamics, contact, fatigue, thermal/electrical coupling, load/constraint definitions, optimization, and forming-limit analysis.

## Why It Matters

For this vault's custom-solver thread, midas NFX is a useful reference because it exposes a broad production FE solver contract without being only bridge-specific. It complements [[midas FEA]] by adding more general structural, thermal/electrical, optimization, and forming-limit coverage, and complements [[midas Civil]] by focusing on solver-kernel mechanics rather than civil design utilities.
