3D curve: about
Introduction
The different quantities calculated in Flux can be graphically represented in function of two other parameters. This representation can be displayed on a 3D curve.
We distinguish three types of 3D curve:
 The curves called « spatial »
 The curves called « transient » or « parametric »
 A mix between « spatial » and « parametric/transient »
Types of 3D curves
The types of 3D Curves are presented in the table below.
Type  Description 

3D Curve (2D grid) 
Graphic representation of one or more spatial quantities in function of the position on a 2D grid 
3D Curve (two I/O parameters) 
Graphic representation of one or more spatial or global quantities in function of two variable parameters (two I/O parameters) 
3D Curve (path + I/O parameter) 
Graphic representation of one or more spatial quantities in function of the position along a path and a progress parameter (I/O parameter) 
Operation
The general process contains the following phases:
Stage  Description 

1 
The user creates a 3D curve defining:

2 
The software creates the 3D curve, the software:
performs the data storage 
3 
The user can:
… 
Reminder of the operation of the curves
Once the curve has been created, the 3D curves like the 2D curves are independent of the scenario step.
The user can change the step and the already created curves will not be modified.
In 3D curves like to 2D curves, there is a tab called context of creation (in the curve management zone) that centralizes the creation information of the curve.
Restrictions
Here are some restrictions :
 The specific values (average, rms value, min, max…) that can be found in a 2D curve are not given for a 3D curve.
 As with the 2D curves, it is impossible to modify a 3D curve (except for the name and comment).
 The derivatives and integrals are not possible.
