This paper presents an original algorithm for the simulation of seismic waves in models containing geological formations with complex properties such as anisotropy, attenuation, and small-scale inhomogeneities. Each of these structures requires special treatment: either small grid steps or computationally intense models and algorithms. These formations typically take as little as 25% of the model; thus computationally expensive approaches are only used locally, while more efficient algorithms are applied elsewhere. The designed hybrid algorithm is heterogeneous; the main focus of this research is the development of an efficient parallel implementation via domain decomposition.
