Beschreibung
Der Befehl FEM NetzForm kann verwendet werden, um die Gittergröße innerhalb und außerhalb einer geometrischen Form (Quader, Kugel oder Zylinder) festzulegen.
Aufgaben-Fenster des MeshShape-Werkzeugs
Anwendung
- To enable the command a
Mesh From Shape by Gmsh must be provided first. - Select the Mesh object in the Tree View.
- There are several ways to invoke the command:
- Press the
Shape-Based Refinement button. - Select the Mesh → GMSH Refinements → Shape-Based Refinement option from the menu.
- Press the
- Edit the size inside and outside of the shape as well as the thickness of the transition layer between the in/out mesh sizes (added outside of the shape).
- Select the shape from the drop-down list and adjust its location and size using the input fields or 3D View draggers:
- Box - set the center coordinates, length, width and height
- Sphere - set the center coordinates and radius
- Cylinder - set the center coordinates, axis and radius
- Click the OK button.
- Close the task.
- Result: You now should see a new
Shapeobject under theFEMMeshGmshobject in your active analysis container.
- Result: You now should see a new
- Double-click on the
FEMMeshGmshparent object in your Model Tree and press Apply to force a mesh recalculation. - Close the task.
Nachdem das Netz erstellt wurde, können seine Eigenschaften mit der Eigenschaften-Ansicht geändert werden. Nachdem eine Eigenschaft geändert wurde, muss der Gmsh-Dialog erneut geöffnet werden und auf die Schaltfläche Anwenden gedrückt werden. (Der Dialog kann während der Änderung der Eigenschaften geöffnet bleiben.)
Es können so viele verschiedene formbasierte Verfeinerungen wie nötig erstellt werden.
