Introduction
"Atelierul MEF" oferă un flux modern de analiză prin metoda elementelor finite (MEF) pentru FreeCAD. În principal, acest lucru înseamnă că toate instrumentele pentru a face o analiză prin Metoda Elementului Finit sunt combinate într-o singură interfață grafică.



Workflow
Pașii pentru a face AEF în Atelierul AEF din FreeCAD GUI sunt:
 * Preprocesare
 * Modelarea geometriei, în care FreeCAD este deja un software aproape dezvoltat.
 * Creați o analiză:
 * Creați o Plasă AEF din modelul geometric.
 * Adăugați la modelul de analiză constrângeri, cum ar fi sarcini și corecții de asistență.
 * Adăugați un material la modelul de analiză
 * Rezolvarea
 * Rezolvați sistemul de ecuații din cadrul GUI-ului FreeCAD.
 * Postprocesare
 * Vezi rezultatele din FreeCAD GUI.

Începând cu versiunea 0.15 a FreeCAD, modulul AEF poate fi folosit pe platforme Windows, Mac OSX și Linux. Deoarece Atelierul AEF folosește software extern, cantitatea de intervenție manuală până când Atelierul AEF este gata de utilizare va depinde de sistemul de operare pe care îl utilizați.
