# Engineering Mathematical Models

## Definition

Engineering mathematical models are idealized descriptions of physical systems, including geometry, material behavior, loads, boundary conditions, constraints, and the governing equations selected for analysis.

## How It Works

The analyst chooses a model that is simple enough to solve and rich enough to answer the engineering question. A finite element solution then approximates that selected model. If the model is poorly chosen, a numerically accurate result can still be physically misleading.

## Why It Matters

The source positions finite element analysis as part of an iterative engineering process: define the model, solve it, assess the result, compare against expected physical behavior, and refine the model when needed.

## Connections

- [[Finite Element Method]] solves mathematical models after discretization.
- [[Mixed Finite Element Formulations]] and [[Nonlinear Finite Element Analysis]] are needed when the chosen model includes constraints, incompressibility, contact, or nonlinear material response.
