Fast multipole method for poroelastodynamics

Here, a fast multipole BEM is proposed to circumvent those points. The Chebyshev interpolation-based FMM significantly reduces the memory consumption of the system matrix and thus allows for larger problem sizes to be treated. As well, it requires fewer evaluations of the fundamental solution. To employ an iterative solver, the use of a transformation of the material data is mandatory. Numerical tests show the expected almost linear complexity of the proposed method.
