Linear Acoustics 4: PAC-MAN
<p>The PAC-MAN geometry is the two-dimensional equivalent to the three-dimensional cat’s eye geometry. As shown in Fig. 1, it is a circle of radius with an angular cut-out ranging from (measured from the x-axis) and. An analytical solution of the sound field inside the cut-out and outside the PAC-MAN has been derived in <a href="http://www.sciencedirect.com/science/article/pii/S0021999117304631?via%3Dihub">Ziegelwanger-Reiter-JCP</a>. The PAC-MAN problem is suited for radiation and scattering.</p> <p>The description with references can be found in the PDF.</p> <p>H. Ziegelwanger and P. Reiter, Analytic formulation of radiated and scattered sound, can be found in the ZIP file.</p>
Linear Acoustics 2: Cat's eye
<p>This benchmark problem consists of a vibrating surface, which coincides with the spherical one. The plain surfaces of the missing octant are assigned a zero admittance. Thereby, the radiator allows construction of a smooth solution that will make it easy to identify solution failures caused by the ill–conditioning of the integral operator for techniques that solve the Helmholtz equation in an integral formulation, i.e. the irregular frequencies. Furthermore, the cat’s eye structure is a more complicated shape than a sphere and hence, the solution is expected to expose more irregular frequencies in a BEM solution than the sphere.</p> <p>A detailed description with references can be found in the PDF description.</p> <p><strong>Available solutions:</strong></p> <p>Steffen Marburg's solution using the Boundary Element Method: LA_Case2_CatEye_SteffenMarburg.pdf</p>
Linear Acoustics 3: Radiatterer
<p>A radiatterer is a geometry that both acts as a radiator of sound as well as it scatterers the radiated sound waves. In addition to the problem of irregular frequencies, it is well suited to compare resonance amplitudes yielded by different methods and different types of finite and boundary elements. Furthermore, the numerical methods should investigate whether mesh refinement in regions with large gradients is necessary or can be neglected.</p> <p>A detailed description with references can be found in the PDF description.</p> <p><strong>Available solutions:</strong></p> <p>Steffen Marburg's solution using the Boundary Element Method: LA_Case2_Radiatterer_SteffenMarburg.pdf</p>
Linear Acoustics 1: Duct 01
<p>This benchmark problem may be considered as waves traveling through a duct. Although a smooth solution is expected over the entire frequency range, the numerical solution may be unstable if modes perpendicular to the traveling waves occur.</p> <p>This benchmark can be used to study the eigenvalue problem with arbitrary admittance boundary conditions, discusses the accuracy of mode superposition for reconstruction of the solution in frequency domain, as well as study the convergence of your formulation towards h- and p-refinement.</p> <p>A detailed description with references can be found in the PDF.</p>
Linear Acoustics 5: BRAS
<p>The Benchmark for Room Acoustical Simulation (BRAS) contains seven acoustical reference scenes that are intended for the evaluation of room acoustical simulation software. The reference scenes isolate acoustic phenomena such as reflection, scattering, and diffraction.</p> <p>For the scientific publication by Aspöck, Lukas; Brinkmann, Fabian; Ackermann, David; Weinzierl, Stefan; Vorländer, Michael we refer to <a href="https://doi.org/10.1016/j.apacoust.2020.107867">https://doi.org/10.1016/j.apacoust.2020.107867</a> and all details can be found at <a href="https://dx.doi.org/10.14279/depositonce-6726.3">https://dx.doi.org/10.14279/depositonce-6726.3</a>.</p>
