# Mesh point: definition (structure)

## Definition

A mesh point is defined by:

- a name (and a comment)
- a type
- specific charateristics, depending on the type
- a color

## Name

The name to identify the mesh point is set by the user during the creation of this one.

A comment (optional) can be added to the name.

## Type

The types of mesh point are presented in the following table.

Type | Description |
---|---|

Uniform | Mesh point using a fixed value determined by the user |

Dynamic* | Mesh point using a dynamic value: the lowest weight corresponds to the length of the shortest incident line of the project. |

## Value

The mesh point value is defined using an algebraic expression that can contain:

- constants
- geometrical parameters
- basic mathematical functions using operators: +, -, *, /, ( )
- usual mathematical functions admitted by FORTRAN.

The mathematical functions are described in section Functions .
