Ansys CFX
Software potente e flessibile per la CFD e multifisica, con particolare focus sulle turbomacchine
Il software Ansys CFX è un solutore CFD a volumi finiti di comprovata accuratezza ed affidabilità.
Grazie alla sua vasta libreria di modelli e alle sue elevate prestazioni, CFX può essere utilizzato per simulare una gamma molto ampia di problemi di fluidodinamica e multifisica.
All’interno di Ansys, CFX è il software CFD di riferimento nel settore delle turbomacchine, dove trova la sua maggiore applicazione grazie
alle sue caratteristiche di accuratezza, stabilità e velocità.
Pompe, ventilatori, compressori e turbine possono essere tutti simulati ed ottimizzati con Ansys CFX, sfruttando modelli appositi allo stato dell’arte e il
calcolo in parallelo su diversi processori.
I numerosi modelli fisici e il solutore numerico sono inglobati in un’interfaccia grafica intuitiva e flessibile, con ampie possibilità di personalizzazione e automazione, che fanno uso di espressioni e file di sessione per poter replicare le operazioni.
All’interno della suite Ansys per il mondo delle turbomacchine ci sono due ulteriori strumenti che completano e semplificano l’impostazione di un’analisi CFD.
Ansys BladeModeler è specializzato nella modellazione rapida dei componenti delle macchine rotanti: permette infatti la creazione della geometria 3D parametrica di componenti assiali, a flusso misto e radiali.
Ansys TurboGrid mette a disposizione una serie di strumenti automatizzati per la generazione di griglie di calcolo strutturate di elevata qualità, favorendo l’accuratezza e la stabilità della soluzione CFD anche di geometrie e forme molto complesse, tipiche di alcune turbomacchine.
