COMSOL expands range of Multiphysics Modeling Tools with version 5.3a

COMSOL 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 material models to a revolutionary method for capacitively coupled plasma 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.

COMSOL 5.3a offers acoustics analysis based on the boundary element method. 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.

A framework for model reduction is available with the release of two methods, modal analysis and asymptotic waveform evaluation, for the reduction of the computational complexity of mathematical models. Customers using LiveLink for MATLAB can get access to reduced models through a dedicated state-space export function. Many customers, especially those involved with computational fluid dynamics analysis, will experience up to 40% improved performance for algebraic multigrid and 20% for geometric multigrid solvers. Support for 3Dconnexion SpaceMouse devices makes model navigation easier. The color table Cividis, optimized for people with color vision deficiency, is now available for visualization of field quantities. Chemical engineers will benefit from the built-in library for thermodynamics properties, which features models for gases, liquids, and phase equilibria (gas-liquids).

A revolutionary new method for modeling capacitively coupled plasmas (CCP), based on a non-linear time-periodic formulation, reduces solution times of CCP simulations from weeks to hours. Those working in electromagnetics can now use the boundary element method to analyze magnetic fields in models with large volume-to-surface ratio, including infinite domains, with great accuracy.

Engineers designing smart metal devices, from biomedical to consumer products, can now include a shape memory alloy (SMA) material in their simulations. A SMA material can be coupled to other physics such as heat transfer. Users will benefit from a solid-beam connection feature as well as a new technique to model thread forces for bolts using a dedicated type of contact pair boundary condition.

Apps with very large plots or many graphics windows will see improved rendering performances resulting in a more responsive user interface. COMSOL Server users will now have the option to login without a password within their corporate network, making it quicker and easier to run apps. The thumbnail image and description for an app can now be changed directly through the COMSOL Server web interface. Administrators can send global notifications to all users, for example, if the server needs to shut down for maintenance. There is a new cluster verification app installed by default in COMSOL Server that allows administrators to test cluster settings more conveniently. This app is also available in a regular COMSOL Multiphysics installation for floating network licenses.

COMSOL Multiphysics and COMSOL Server software products are supported on Windows operating system, Linux operating system, and macOS operating system. The Application Builder is supported in the Windows operating system.
