The Boundary Element Method (BEM) requires the solving of large, ill-conditionned, dense linear systems with a large number of righ-hand sides ; the solving difficulty is the main practical obstacle to its use. A hierarchical matrix (ℋ´Matrix) is a hierachical, approximate, data-sparse storage format for matrices that can be manipulated to produce a direct linear solver with an asymptotic space and time complexity of O(N log α2 (N)). We consider the ℋ´Matrices for the BEM, with the assessment and application of ℋ´Matrices to complex academic and industrial test cases on the one hand ; and the efficient parallelization of these algorithms on the other hand. A rigorous and detailed parametric study on model and industrial test cases is shown....
