3D curve: about


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)


The general process contains the following phases:

Stage Description

The user creates a 3D curve defining:

  • a name
  • a quantity on the X axis (path, 2D grid, I/O parameter)
  • a quantity on the Y axis (2D grid, I/O parameter)
  • one or more quantities on the Z axis

The software creates the 3D curve, the software:

  • computes the values corresponding of curves required by the user
  • opens a specific tab to display the 3D curve
  • displays the required 3D curve

performs the data storage


The user can:

  • change the mod of representation (2D graph or 3D graph)
  • use the visualization functionalities
  • export the calculated values

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.


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.
