# Modeling software

## Definition

**Modeling software** (or **modelling software** in UK English) is a computer program to build simulations or other models.

Modeling software relies on a modeling language, that “is any artificial language that can be used to express information or knowledge or systems in a structure that is defined by a consistent set of rules. The rules are used for interpretation of the meaning of components in the structure. A modeling language can be graphical or textual.” [1]

Modeling languages can be used by instructional designers/technologists or even teachers to produce teaching materials (e.g. simulations). Learners also can be engaged into modeling activities.

## Types of modeling software

This an incomplete inventory for now. See Wikipedia:Model for an overview of what a model could be and follow links ...

### Microworlds

- Most microworlds allow both teachers and students to build models. See microworlds and Programming microworld.

### Mathematical systems simulation

- System dynamics software
- Mathematica-like systems
- Spreadsheets

### Special simulation software

E.g.

- Network configuration
- molecular modeling (HyperChem, Spartan, CAChe, PC Model, etc.)
- Mechanical dynamics
- Climate modeling, e.g. EdGCM
- Business processes
- Production chain modeling.

### 3D Modeling

- All sorts of 3D CAD programs (Solidworks, Rhinoceros, Autodesk AutoCAD, 123D, TinkerCad, etc.)
- General purpose 3D modeling software
- 3D programs specialized to build models for 3D environments (virtual reality, computer games, etc.
