COMSOL Multiphysics version 6.0 introduces the Model Manager, the Uncertainty Quantification Module, faster solvers for heat radiation and nonlinear structural materials, new powerful tools for electromagnetics analysis of PCBs, and flow-induced noise.
Of course, this major software release is much more than the Acoustics Module. The image shows a car door model in the Prism color table. And there are also several new and improved color tables to further expand the range of visualization capabilities. Flow-induced noise capabilities also now have a new dedicated multiphysics coupling and transient mapping study, while speaker designers will benefit from a new Lumped Loudspeaker boundary condition and sector symmetry options in the exterior field feature.ĬOMSOL Multiphysics v6 offers the ability to make geometry appear more realistic with the new Ambient Occlusion option available in the Graphics window toolbar. Listed as the main features for the updated Acoustics Module are the new Piezoelectric Waves, Time Explicit multiphysics interface based on the discontinuous Galerkin (dG) time-explicit method, and two new high-frequency pressure acoustics interfaces for modeling scattering and radiation, based on the high-frequency BEM (HFBEM) method.
Other optimizations include an improved UI for parameter estimation and a Transformation shape optimization feature for simple changes, i.e. COMSOL 6.0 also makes gradient based optimization with a transient solver more robust by adding a transient topology optimization model to the Application Library. Among many new features, users of the COMSOL Multiphysics 6 Acoustics Module will enjoy the possibility to model piezoelectric phenomena in the time domain for wave propagation using a time-explicit formulation, physics-controlled mesh for pressure acoustics problems, new high-frequency wave methods, and the flow-induced noise capabilities using hybrid CAA with Lighthill's analogy.
