Geometric parameter: definition (structure)
Definition
A geometric parameter is defined by:
- a name (and a comment)
 - an algebraic expression
 
Name
The name to identify the geometric parameter is set by the user during the creation of this one.
A comment (optional) can be added to the name.
Algebraic expression
The algebraic expression can contain:
- constants
 - geometric parameters (created beforehand)
 - basic mathematical functions using operators: +, -, *, /, ( )
 - usual mathematical functions admitted by FORTRAN
 
The mathematical functions are described in section Functions.
