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
- To enable the function a mesh must be first provided FEM mesh from shape by Gmsh
- Then select the Mesh object in the Tree view and either
- 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.
- Click the OK button.
- Close the task.
- Result: You now should see a new
FEMMeshGroup
object under theFEMMeshGMSH
object in your active analysis container.
- Result: You now should see a new
- Double-click on the
FEMMeshGMSH
parent object in your Model Tree and press Apply to force a mesh recalculation / relabeling. - 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.
