Solution of large scale elastic problems with the boundary element method : applications to infrasound and micro-seismicity generated by wind turbines
… static as well as harmonic problems based on the hierarchical matrix methodology combined with the algebraic low rank approximation technique, known as Adaptive Cross Approximation (ACA), is proposed. For the efficient algebraic compression of the utilized hierarchical matrices, different versions …

Solution of a Second Order Elliptic Partial Differential Equation with Varying Complex Coefficients: An Application for Computing Effective Complex Electrical Properties of Materials represented by 3D Images
… The solution is computed using the technique of Hierarchical Matrices in combination with a Linear Method and the Generalised Minimal Residual Method algorithm. A C code was written to implement the scheme. The code uses the NetCDF library to read the 3D image and the H-Lib(Pro) library to work …
