Import of a curve starting from a formatted file

Introduction

The user can import a curve starting from a formatted file via the command Import 2D curve – formatted file or Import 3D curve – formatted file.

Command access

The dialogue box associated to the command:

  • Import 2D curve – formatted file is generic to 3 types of 2D curve and is accessible in the menu Curve by pointing on one of the types-entities 2D curve (path, I/O parameter, material).
  • Import 3D curve – formatted file is generic to 3 types of 3D curve and is accessible in the menu Curve by pointing on one of the types-entities 3D curve (2D grid, path + I/O parameter, 2 I/O parameters).

Principle

Here are some rules of operation necessary to understand the use of this command:

  • The user chooses a formatted file *.txt (see section below).
  • The user chooses the curve name .
  • The user chooses the curve type so that the imported curve should be automatically stored in the corresponding type of the 2D Curve entity (path, I/O parameter and material) or the corresponding type of the 3D Curve entity (2D grid, path + I/O parameter, 2 I/O parameters).
  • The user specifies the column separator used in the formatted file*.txt if this is different from « tab » , « space » , « ; ».

Formatted txt file

Here is the format to use in the file so that the importing of a curve starting from a formatted file should be possible:

Note: the formatted txt file can contain several quantities to import.

There will be N-1 imported curves for a file containing N columns (the first column being reserved to the parameter in abscissa).

Import a formatted curve

To import a 2D curve or a 3D curve starting from a formatted file:

Etape Action
1 Open the dialogue box Import 2D – formatted file or Import 3D curve – formatted file
2 Choose the file to import (formatted file*.txt )
3 Choose the curve name
4

Choose the curve type :

  • (path, I/O parameter and material) for a 2D curve
  • (2D grid, path + I/O parameter and 2 I/O parameters) for a 3D curve
5 Choose the used column separator (if it is different from « tab », « space », « ; » ; else directly go to step 6)
6 Validate by clicking on OK
→ The curve is created, displayed and stored in the required type of curve.
