Acoustic simulations become a more and more important toolset for industry and research. For a few years now, our institute uses COMSOL Multiphysics for numerical simulations, e.g. FEM and BEM, in various fields of acoustics. For proper processing of simulation results, we usually rely on MATLAB and the ITA-Toolbox. Although COMSOL provides a MATLAB interface (LiveLink), using this for advanced processing is not straightforward. With this in mind, I designed a user-friendly interface between the ITA-Toolbox and COMSOL. It allows an efficient retrieving of simulation results at user-defined coordinates using the itaResult format. Additionally, frequency-dependent data, e.g. a measured boundary impedance, can be applied to COMSOL models.

In this colloquium, which is a mix of presentation and live demonstration, the ITA-Toolbox COMSOL interface is introduced. First, the motivation behind this implementation as well as its key features are discussed. Then, those features are presented in small, interactive live demos. Feel free to ask questions during the demonstration.
