FEM ConstraintSelfWeight/fr

Description
Le poids propre de la contrainte définit l’accélération de la gravité 9,81 m / s ^ 2 agissant sur l’ensemble du modèle dans la direction prescrite.

Utilisation

 * 1) Click on [[Image:FEM ConstraintSelfWeight.png|32px]] or choose → Mechanical Constraints →   from the top menu or press  then  keys.
 * 2) You can modify the direction of gravitation by changing its vector coordinates in the property bar of newly created ConstraintSelfWeight object.


 * 1) Cliquez sur [[Image: FEM ConstraintSelfWeight.png | 32px]] ou choisissez →  'Contraintes mécaniques'  →  dans le menu supérieur ou appuyez sur les touches, puis.
 * 2) Vous pouvez modifier la direction de la gravitation en modifiant ses coordonnées vectorielles dans la barre de propriétés du nouvel objet ConstraintSelfWeight.

Limitations

 * You need to modify .inp file to edit gravity acceleration.
 * Self weight is applied to the element set Eall means to the whole model.

Editing CalculiX input file
Acceleration constant can be edited by hand modification after generating CalculiX input file.

Example of lines in .inp file:

where 9810 is gravity acceleration in [mm/s^2]
