Abstract
We extend the source transfer domain decomposition method (STDDM) proposed by Chen et al., in order to solve the time-harmonic elastic wave equation that is discretized using the spectral element method. Some numerical examples are presented, demonstrating that STDDM can be applied as an efficient preconditioner in the preconditioned GMRES method for solving the PML equation of the time-harmonic elastic wave equation, with constant and heterogeneous wave numbers. Regarding the problem with constant wave number, the preconditioned GMRES method converges within just a small number of iterations when the discretization error is reduced by high order spectral elements.
