Abstract:
A mo rtar- type ro tated Q1 e lem ent m ethod is discussed for nonsymm etric and indefin ite prob lem s. A m ultigr id a lgor ithm is proposed fo r the discre te system s wh ich g ives an optim al convergence factor, .i e. , the convergence rate is independen t of the m esh size and m esh leve.l Num e rica l results con firm our theo retical analysis
