Update of a multiphysics spatial quantity by import

Introduction

To implement data exchanges by multiphysics, the user needs to update a multiphysics spatial quantity by means of the command Update multiphysics spatial quantity by importation.

Imported file

A multiphysics spatial quantity can be updated by the import of a file containing data at each node. Different formats are available :

Format Description
*.DEX

DEX = Data EXchange

format specific to Flux
*.IP IP is a format for the Fluent software
Tabulated The user enters the coordinates of the points manually

Importation options

If the nodes of the selected support are different from the imported file points, the user has to chose an importation option between:

Importation option Description
Node to node  
By proximity

Permits to take the node located at the nearest point of the file.

The user has to specify the maximum distance allowed between the nodes and the points of the file.

Update of a spatial quantity

To update a multiphysics spatial quantity by importation:

Step Action
1

In the menu Parameter/Quantity:

  • point on Spatial quantity
  • activate the command Update multiphysics spatial quantity by importation
→ A dialog box «Update multiphysics spatial quantity by importation» is opened
2 Choose the Tabulated spatial quantity to be updated
3

Choose the support for the import:

  • Choose the type of region (surface or volume)
  • Choose the region
4

Specify the file to import:

  • Choose the format (DEX, IP or tabulated)
  • Choose the file to import, or define the coordinates of the points if the chosen format is «tabulated»
5 Choose the position of the mechanical set (if any)
6

Choose the import option between:

  • Node to node

or

  • by proximity: Specify the maximum authorized distance between the nodes and the points of the file
