Boundary Element Methods for the Wave Equation based on Hierarchical Matrices and Adaptive Cross Approximation
Daniel Seibel
Time-domain Boundary Element Methods (BEM) have been successfully used in acoustics, optics and elastodynamics to solve transient problems numerically. However, the storage require…
