Descrizione
Crea un elemento FEM di sezione del fluido per le reti pneumatiche e idrauliche risolto con CalculiX.
Utilizzo
- Esistono diversi modi per richiamare il comando:
- Premere il pulsante
Sezione fluido per flusso 1D. - Seleziona l'opzione Model → Geometria dell'Elemento → Sezione fluido per flusso 1D dal menu.
- Premere il pulsante
- Selezionare il tipo di fluido: liquido, gas o canale aperto
- Selezionare il tipo di sezione: Pipe Manning (coefficiente di scabrezza), Pipe Inlet (tubo di aspirazione) ecc.
- Inserire i parametri del tipo di sezione.
- # Premere il pulsante Aggiungi. Selezionare i bordi. disponibile dalla versione 1.1: Per rimuovere i bordi dalla selezione, premere il pulsante Rimuovi.
Limitazioni
- Funziona solo con un elemento di rete a 3 nodi. Le informazioni possono essere trovate in: http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node54.html
Note
- Un esempio di impostazione di una rete idraulica è disponibile in: http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node13.html
- La *scheda FLUID SECTION viene utilizzata per modellare elementi fluidi per il flusso 1D.
