In the Application Builder, app designers can now define customized actions when clicking on plots in graphics objects, enabling the easy creation of interactive apps. Updates to COMSOL Server include comprehensive log files for user activity as well as a centralized cluster administration setting in the COMSOL Server web interface for easy setup of running apps on clusters. The app interface can be easily customized and accessed via a browser or a Windows client, which connects to a local installation of COMSOL Server. The Application Builder allows simulation specialists to create apps based on their multiphysics models. Coupled acoustic and structural propagating mode in a muffler chamber with thin elastic walls. For example, you can create a reusable model method that generates a complicated array of geometric objects to expand on the standard functionality of the Model Builder", continues Sjodin.ĬOMSOL Acoustics Module in V5.3. This is an important usability feature with many possible applications. "You can now simply record a set of operations, like a macro, and use the resulting method while setting up or solving a model. With the introduction of model methods in version 5.3, it is easy to automate repetitive operations directly in the Model Builder. This is not only about solution time but also how the software handles large models in the user interface, including geometry and mesh", comments Bjorn Sjodin, VP of Product Management, COMSOL. "We continue to see improved performance for large models across the board. A new option for automatic geometry defeaturing through virtual geometry operations is now available to users. Users working with models and geometry requiring the use of several element types will benefit from the automatic generation of pyramidal elements to handle the transition between swept, hexahedral, prismatic, and tetrahedral meshes. The Model Builder now more rapidly handles geometry and mesh operations for models with large arrays and complicated solid operations in 3D. This feature blends high-fidelity low-Reynolds formulation with wall functions. Users modeling turbulent flows can benefit from more robust computations with the automatic treatment of walls. The AMG solver requires only a single mesh level and is now the default option for many fluid flow and transport phenomena interfaces. Users handling large CFD models will benefit from the new algebraic multigrid (AMG) solver implemented in version 5.3. Typical uses for this functionality include the modeling of electrical cathodic protection, cables, or capacitive sensors. The Boundary Element method enables users to simulate models with infinite domains and voids, as well as to quickly set up simulations that combine wires, beams, surfaces, and solids in the same model. "This means that users can easily combine boundary element and finite element methods for greater flexibility in their multiphysics simulations", continues Littmarck. With COMSOL version 5.3 the boundary element method (BEM) is now available for modeling electrostatics and corrosion effects. Our users will find great value in new solvers, the new physics interfaces, and the many enhancements throughout COMSOL software, from model creation to deployment of apps", comments Svante Littmarck, President and CEO, COMSOL.Īpart from the always important performance improvements, highlights of new features and tools available in Version 5.3 include new physics for Thermoviscous Acoustics, Transient, and Poroelastic Waves, new particle tracing options and much more. "Version 5.3 is a result of our continued focus on delivering highly capable mathematical modeling tools. In many cases, users will experience a speedup of ten times or more in software responsiveness, such as in preprocessing tasks for handling models with several thousand boundaries and domains. There are hundreds of new and exciting features in the new COMSOL software for electromagnetics, structural, acoustics, fluid, heat, and chemical simulations. Vibration and noise analysis in a 5-speed synchromesh gearbox inside a manual transmission vehicle.Īs COMSOL explains, version 5.3 is a major release that benefits simulation specialists with faster model and app development, shorter solution times, and new physics, increasing research and development throughput across all industries.
