Descrizione

Da fare

FEM MeshGroup therefore enables FreeCAD to be used with external solvers (or viewers such as ParaView) when they are not yet implemented with their own case-writing routine within FreeCAD.

Utilizzo

  1. To enable the function a mesh must be first provided FEM mesh from shape by Gmsh
  2. Then select the Mesh object in the Tree view and either
    • Press the FEM mesh group button in the FEM toolbar
    • Select the Mesh → FEM mesh group option from the drop-down menu.
  3. Select whether the group is named or labeled
    • If Name is selected, the name of the MeshGroup is used when exporting the mesh.
    • If Label is selected, the specified label name will be used when exporting the mesh.
  4. Click the Add button and select the geometrical entity (solid, face, edge or vertex). More such objects can be added but they have to be of the same type. The mesh group will consist of underlying mesh entities.
  5. Click the OK button.
    Result: You now should see a new FEMMeshGroup object under the FEMMeshGMSH object in your active analysis container.
  6. Double-click on the FEMMeshGMSH parent object in your Model Tree and press Apply to force a mesh recalculation / relabeling.
  7. Close the task.

Notes

  • After the mesh has been created, you can change the label property using the property editor.
  • After you change a property, you must reopen the Gmsh dialog again and click the Apply button (you can leave the dialog open while changing properties).
  • You can create as many different mesh groups as needed.
  • By default, mesh groups can only be exported to .med and .unv formats. To be able to export them to the .inp format, one needs to enable the Export group data option in INP export preferences.
