Figure 2. Time-domain wavefield snapshots for a point source with Hz peak frequency in velocity fields with different random boundary conditions. The top row shows one realization of velocity with a) constant velocity, b) cubic grains with m side length, c) cubic grains with m side length, and d) randomly shaped grains with effective length m. The bottom row shows average wavefields using realizations of velocity with e) constant velocity, f) cubic grains with m side length, g) cubic grains with m side length, and h) randomly shaped grains with m effective length.
