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 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 OK button.
5. Close the task.

   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 changed 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.
