A hierarchical BEM solver for the analysis of three-dimensional anisotropic time-harmonicfracture mechanics problems is presented. A thorough investigation on the relations and interactionsbetween the numerically computed anisotropic fundamental solutions and the algorithm used toapproximate the blocks of the hierarchical matrix, namely Adaptive Cross Approximation, is carried outleading to the employed computational strategy. The use of the hierarchical matrices and iterative solvers isproved as an effective technique for speeding up the solution procedure and reducing the required memorystorage in time-harmonic three-dimensional anisotropic fracture mechanics problems.
