As of FreeCAD 0.15 the FEM Workbench can be used on Windows, MacOSX and Linux platforms. Since the workbench makes use of external solvers, the amount of manual setup will depend on the operating system that you are using. See the [[FEM_Install|FEM Install]] page for instructions on setting up the external tools.
The above mainly describes how a FEA analysis is done inside FreeCAD FEM Workbench. For further documentation refer to the GUI Tools described later here.

As of FreeCAD version 0.15 the FEM-Module can be used on Windows, Mac OSX and Linux platforms. Since FEM Workbench makes use of external software, the amount of manual intervention until the FEM workbench is ready to use will depend on the OS that you are using. Check out [[FEM_Install|FEM Install]].

Introduction

Der Arbeitsbereich FEM ermöglicht die effiziente Bearbeitung einer Finiten Element Analyse (FEA) innerhalb von FreeCAD. Es stehen alle Werkzeuge zur Durchführung einer Finiten Element Analyse in einer Benutzeroberfläche zur Verfügung.

Workflow

Die Arbeitsschritte zur Erstellung einer FEA in dem FreeCAD-FEM-Arbeitsbereich umfassen:

  • Vorbereiten (Preprocessing)
    • Erstellen einer Geometrie, hierzu werden die in FreeCAD vorhandenen Werkzeuge außerhalb des FEM-Arbeitsbereiches benutzt.
    • Anlegen einer Analyse:
      • Erzeugen eine FEM-Netzes aus dem geometrischen Modell.
      • Einwirkende Lasten sowie Halterungen dem Modell hinzufügen.
      • Eine Materialdefinition mit der Geometrie verknüpfen
  • Lösen
    • Innerhalb der FreeCAD-Oberfläche die Lösung des Gleichungssystems starten.
  • Nachbereiten (Postprocessing)
    • Anzeige der Ergebnisse innerhalb in FreeCAD.

As of FreeCAD 0.15 the FEM Workbench can be used on Windows, MacOSX and Linux platforms. Since the workbench makes use of external solvers, the amount of manual setup will depend on the operating system that you are using. See the FEM Install page for instructions on setting up the external tools.

Menu: Model

  • Analysis container: Creates a new container for a mechanical analysis. If a solid is selected in the tree view before clicking on it, the meshing dialog will be opened next.
