Dual system least squares finite element method for the Helmholtz equation
This paper uses LL∗method to solve Helmholtz equation in case when the frequency parameter is large. The Helmholtz equation is reformulated to the first order system by introducing a new variable and then the corresponding dual problem is considered. The unique existence to the weak solution of the...
