000020227 520__ $$2eng$$aDirect numerical simulation of wave propagation in highly heterogeneous media demands very fine discretization in space and time, and scalability of all steps of a numerical simulation, including the pre- and post-processing. In this paper, we integrate the following elements in a scalable parallel workflow: an octree meshing scheme, a random field generator for mechanical properties, and a spectral element solver for wave propagation. The hexahedral meshing algorithm includes the consideration of topography, bathymetry, coastlines and wave velocity variation with depth. The random field generator allows to modify locally (in space) the value of a given realization. Numerical simulations and scalability studies are presented for each and all components of the seismic simulation workflow.
