Introduction

Bancada FEM proporciona um moderno entorno para o Analise de Elementos finitos (AEF) para FreeCAD. Principalmente isto significa, que todas as ferramentas para realizar o Analise de Elementos Finitos   estão arrumadas no mesmo entorno gráfico (GUI).

Workflow

Os passos para fazer um FEA na bancada de trabalho "FEM Workbench" são:

  • Pré-processamento
    • A modelagem da geometria, na qual FreeCAD já é um software consolidado.
    • Criar uma Análise:
      • Criar uma malha FEM fora do modelo geométrico.
      • Adicionar restrições tais como cargas e fixar os apoios para o modelo de análise.
      • Adicionar um material para o modelo de análise
  • Solucionar
    • Resolver o sistema de equações de dentro do FreeCAD GUI.
  • Pós-processamento
    • Ver os resultados dentro FreeCAD GUI.

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.

Materials

Element Geometry

Electrostatic Constraints

Fluid constraints

Mechanical constraints

  • Constraint force: Used to define a force in [N] applied uniformly to a selectable face in a definable direction.

Thermal constraints

Menu: Mesh

  • Nodes set: Creates/defines a node set from FEM mesh.

Menu: Solve

  • Solver Calculix CCX tools: Creates a new solver for this analysis. In most cases the solver is created together with the analysis.

Menu: Results

  • Result show: Used to display the result of an analysis.

Menu: Utilities

Context Menu
