Descriere
Creează o MEF în secțiunea de fluid pentru rețele aerodinamice și hidraulice
Cum se folosește
- Click on
sau alegeți Model →
Fluid section for 1D flow din meniul de sus.
- Selectați tipul Fluidului: Liquid, Gas or Open Channel
- Selectați tipul de Secțiune: Pipe Manning(coeficientul de rugozitate), Pipe Inlet (tubul de aspirație) etc.
- Entroduceți parametrii tipului de Secțiune.
- Selectați și adăugați muchia.
Limite
- Tabelul funcționează numai cu o rețea tip cu 3 noduri. Informația poate fi găsită aici: http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node54.html
Note
- Un exemplu de set up a rețelei hidraulice poate fi găsit aici: http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node13.html
- Tabelul *FLUID SECTION este utilizat pentru a modela elementele fluide pentru o curgere liniară 1D. Informația de pe tabel poate fi găsită aici: http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node205.html
