“…In one of the early works [24] authors use the on-the-fly approach to accelerate the boundary element method for the Helmholtz equation. More recently, the focus has been on acceleration of the fast BEM techniques, such as adaptive cross approximation [5,25] or fast multipole method [26]. An example of an open-source GPU-accelerated library of BEMbased solvers for the Laplace, Helmholtz, and Maxwell problems is Bempp-cl [2].…”
