Beschreibung
Der Befehl FEM NetzTransfiniteKurve erstellt mithilfe eines strukturierten Algorithmus eine festgelegte Anzahl von Knoten auf einer Kante.
Aufgaben-Fenster des Werkzeugs MeshTransfiniteCurve
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
Structured Transfinite Curve button. - Select the Mesh → GMSH Refinements → Structured Transfinite Curve option from the menu.
- Press the
- Select the type of node distribution on an edge:
- Constant - specify the number of nodes
- Bump - refinement towards both ends of the curve: specify the number of nodes and the coefficient
- Progression - geometrical progression with power x: specify the number of nodes and the coefficient x (e.g. 2 means that each element on the edge will be twice as long as the preceding one)
- Optionally, check the Invert box.
- Press the Add button. Select a vertex, edge or face. To remove objects from the selection, press the Remove button.
- Click the OK button.
- Close the task.
- Result: You now should see a new
TransfiniteCurveobject 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 transfinite Kurven wie nötig erstellt werden.
