CHE SIGNIFICA MULTIGRID IN INGLESE
Metodo Multigrid
I metodi Multigrid nell'analisi numerica sono un gruppo di algoritmi per la risoluzione di equazioni differenziali utilizzando una gerarchia di discretizzazioni. Essi sono un esempio di una classe di tecniche chiamate metodi di multiresoluzione, molto utili nei problemi che presentano scale multiple di comportamento. Ad esempio, molti metodi di rilassamento base presentano tassi di convergenza diversi per componenti a lunghezza breve e lunga lunghezza d'onda, suggerendo che queste diverse scale siano trattate in modo diverso, come in un approccio di analisi di Fourier a multigrid. I metodi MG possono essere usati come solventi così come precondizionatori. L'idea principale del multigrid è accelerare la convergenza di un metodo iterativo fondamentale dalla correzione globale di volta in volta, compiuta risolvendo un problema grossolano. Questo principio è simile all'interpolazione tra griglie più grossolane e più sottili. La tipica applicazione di multigrid è nella soluzione numerica di equazioni differenziali parziali ellittiche in due o più dimensioni. I metodi Multigrid possono essere applicati in combinazione con una delle tecniche comuni di discretizzazione. Ad esempio, il metodo dell'elemento finito può essere ricostruito come metodo multigrid.
definizione di multigrid nel dizionario inglese
La definizione di multigrid nel dizionario riguarda diverse griglie. L'altra definizione di multigrid è che i metodi multigrid sono algoritmi utilizzati per risolvere equazioni differenziali.
