Descrizione
ElementGeometry2D is used to define thickness of 2D FEM elements, all or laying on the chosen surface.
Utilizzo
- Premere il pulsante Spessore di una lastra, o premere i tasti C e poi S.
- Definire un parametro di spessore.
- Opzionalmente, fare clic su
Aggiungi
nel pannello Azioni e poi fare clic sull'icona. Se la selezione della faccia è libera, tutte le facce rimanenti (lo spessore non definito da altri oggetti Spessore di una lastra) vengono assegnate automaticamente.
- Press the FEM ElementGeometry2D button, or press C then S keys.
- Define a thickness parameter.
- Optionally click
Add
in the Task panel and then click on the face you want to have prescribed thickness. If the face selection is free, all remaining faces (which thickness is not defined by other FEM ElementGeometry2D objects) will be automatically assigned.
Limitazioni
- L'analisi combinata di elementi di shell con elementi solidi o bordi non è supportata nella versione corrente (FreeCAD 0.18).
- Analysis combining shell elements with solid or edge elements is not supported in the current version (FreeCAD 0.18).
Proprietà
DatiThickness: specifica lo spessore della shell.
DatiThickness: specifies the thickness of the shell.

Note
Per visualizzare i risultati dal risolutore CalculiX sulla mesh espansa allo spessore prescritto, la proprietà Beam Shell Result Output 3D
in FEM SolverCalculixCxxtools deve essere impostata su True
.
For viewing results from CalculiX solver on the mesh expanded to the prescribed thickness, property Beam Shell Result Output 3D
in the FEM SolverCalculixCxxtools need to be set to True
.
