# 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.
