Descrizione

Si applica un vincolo di pressione a una faccia.

Utilizzo

1. Cliccare su o scegliere Modello → Vincoli meccanici → Vincolo pressione dal menu principale.
2. Cliccare su Aggiungi riferimento e selezionare una faccia nella vista 3D.
3. Specificare un carico di pressione in MPa nella finestra.
4. Se necessario, spuntare la casella per invertire la direzione.

Note

- La distribuzione della pressione sulla faccia è sempre uniforme e sempre perpendicolare alla faccia.
