Calculation of Transient Response of Viscoelastic Unbounded Domains by Direct Boundary Element MethIntegral Equations (BIE) in time domain with the Boundary Element Method (BEM). Thus, the spatial problem dimension is reduced by one. Viscoelastic constitutive behaviour is implemented by means of a Laplace transform technique based on an elastic-viscoelastic correspondence principle. The concept o

Reduction of the Complexity of the Intrisically Nonlinear Problem of Aerodynamic Sound Generation ilem is inherently nonlinear, a unique splitting of the field quantities into acoustic, vortical, and entropy modes exists. The splitting for the nonlinear case is formally produced with projection operators, and as such, the method described in this paper for determining the acoustic portion of a co

Exact and High-Order Boundary Conditions in the Time Domain,l solution of scattering problems in the time domain. An impressive number of schemes have been proposed to overcome this difficulty. Nonetheless, the ideal of solving the problem on a fixed domain and achieving convergence by some systematic improvement of the boundary treatment and/or simple mesh

Benchmark Problems,The participants of the Symposium on Computational Methods for Unbounded Domains formed four working groups of nine members each to work in parallel on benchmark problems. Each group presented its benchmark candidates to the assembly of participants, which initiated a process of consolidation
