P001 ITERATIVE SOLVERS FOR FREQUENCY DOMAIN (VISCO) ACOUSTIC MODELING OF SEISMIC WAVES I. STEKL Summary 1 In order to perform 3D simulations on the hardware available at the moment current approaches in frequency domain are not suitable due to a large amount of memory required to invert the matrix. Point iterative solvers are not converging quickly or not converging at all in the case of the highly oscillatory solutions such is the one of the frequency domain wave equation. In this work I present the results obtained using the appropriate block iterative solver. Frequency domain modelling approach is interesting due
