FEM Module/fr

Introduction
Le module Fem Workbench offre une méthode moderne d'analyse d'éléments fini (Finite Element Analysis (FEA)) pour FreeCAD. Principalement, cela signifie que tous les outils servants à faire une analyse d'éléments finis sont réunis en une seule interface graphique.



Workflow
Les étapes pour faire un FEA dans FreeCAD l'atelier graphique FEM possède:
 * Prétraitement
 * La modélisation de la géométrie, dans laquelle FreeCAD est un logiciel presque à maturité.
 * Création et Analyse:
 * Création d'un Mesh FEM sur le modèle géométrique.
 * Ajouter des contraintes telles que les charges et les correctifs de soutien au modèle a analyser.
 * Ajout de matériel pour analyser le modèle
 * Résolution
 * Résolution du système d'équations à partir de l'interface de FreeCAD.
 * Post-traitement
 * Vue des résultats dans l'interface de FreeCAD.

À partir des versions FreeCAD 0,15 le module FEM peut être utilisé sur les plates-formes Windows, Mac OSX et Linux. L'atelier FEM utilise un logiciel externe, en attendant la finalisation de l'atelier FEM la quantité d'interventions manuelles nécessaire dépendra de l'OS utilisé. Consultez FEM Installation.
