Abstract: Simulation software is increasingly replacing traditional physical testing in the process of product development, as it can in many cases reduce development times and costs. In a variety of applications, the reduction of noise is an important aspect of the product design and using methods from the field of computational aero-acoustics (CAA), the generation and propagation of sound in air may be simulated. In this project, a FEM-based solver for the three-dimensional Helmholtz equation, mo... more
