COMSOL 5.3a expands its multiphysics modeling tools

Editor’s note: This simulation software may be of interest to those designing products for the wind industry. The company says Comsol multiphysics and Comsol server version 5.3a bring more modeling power to users with new numerical methods for multiphysics modeling and app development.  An acoustics simulation feature is highlighted. 

COMSOL, a developer of software for multiphysics modeling and simulation, today made available the latest release of the COMSOL Multiphysics and COMSOL Server products. Version 5.3a provides simulation specialists with cutting-edge modeling tools and increased solver performance. From shape memory alloy (SMA) material models to a revolutionary method for capacitively coupled plasma (CCP) simulations and a hybrid boundary element-finite element (BEM-FEM) method for acoustics and acoustic-structure interaction, customers across all industries and physics areas will benefit from new methods and reduced solution times.

“Our customers strive for a highly efficient product development cycle. With the multiphysics modeling capabilities of our software, they can create innovative products faster and at a lower cost than ever before. This exciting release is a result of a big focus on quality and major advances in new powerful modeling methods, increased speed, and user-driven enhancements,” says Svante Littmarck, President and CEO, COMSOL.

Hybrid boundary element-finite element method for acoustics

By combining boundary element, finite element, and ray acoustics analysis in a multiphysics environment, COMSOL 5.3a delivers unprecedented acoustic modeling capabilities.

COMSOL 5.3a offers acoustics analysis based on the boundary element method. “The recent addition of the boundary element method in COMSOL Multiphysics will enable us to model large acoustical radiation problems, such as exterior sound reproduction for electric cars” comments Martin Olsen, Principal Engineer, Research, at Harman Lifestyle Audio. “We are pleased with the full range of methods available in COMSOL, from FEM and BEM to ray tracing. The possibility of coupling BEM to FEM creates a highly versatile simulation environment for the automotive audio industry.” Acoustic engineers will get unprecedented modeling power by being able to analyze the full range of acoustic frequencies from the lowest bass notes to ultrasound, in addition to all of the possible multiphysics couplings available in the software.
