COMSOL has announced the release of COMSOL Multiphysics version 5.2 providing the simulation community the only fully integrated environment for creating simulation apps. This version of COMSOL Multiphysics and COMSOL Server simulation software environment delivers new features, improved stability and robustness, and faster execution. Major upgrades to the Application Builder available in COMSOL Multiphysics include the new Editor Tools for easy creation of user interface components, commands for dynamic updates of graphics, and more control over the deployment of simulation apps. Running simulation apps using COMSOL Server in a corporate network or in the cloud is now up to five times faster. Many updates, new features and simulation application examples are also available for the add-on electrical, mechanical, fluid, and chemical products.
Clearly Communicate Designs with the Application Builder
In COMSOL Multiphysics 5.2, the Application Builder features an optimised workflow. The new Editor Tools make the creation of user interface components easy and quick. Simulation specialists can now bring any model parameter, physics setting, and results, such as numerical data and plots into the user interface of an app with a few mouse clicks. This is one of several tools available to create practical simulation apps and share the power and accuracy of COMSOL Multiphysics throughout organisations.
The Application Builder allows companies to communicate across multiple departments, knowing that the simulation expert is able to maintain control, enforce quality standards, and ensure that the results can be trusted.
“We leveraged the Application Builder to more efficiently communicate complex design ideas across multiple simulation and process departments, which has allowed app users to easily explore the outcome of proposed designs,” said Borja Lazaro Toralles, Research Engineer on the Manufacturing Technology Centre (MTC) simulation team. MTC used COMSOL products to model the shaped metal deposition (SMD) 3D printing technique and created a simulation app based on it.
Among the new user-inspired features is the ability to update graphics while running an app. The app designer can present app users with different plots while solving; this takes them through the progression of the solution process and presents them, for example, with geometry, mesh, and solution plots. The app designer can also customise the graphics toolbar with new buttons and include camera movements.
Collaborate with COMSOL Server Software
The new features in version 5.2 of COMSOL Server are designed to facilitate collaboration between users and departments while simplifying administration tasks. “A new caching function allows applications to start five times faster or more; additionally, administrators can assign a single application to be launched instantaneously when users log in,” said Ed Fontes, CTO of COMSOL. “These are just few of the many new features and concepts introduced with version 5.2.”
COMSOL Multiphysics version 5.2 provides simulations experts with a cutting edge user experience in simulation app design and sharing by integrating highly productive model building, app design, and deployment tools that allow their simulation applications to be used by users everywhere.
“We’ve been creating simulation apps that our field engineers can apply directly without having to go through R&D,” said Brice McPherson, Senior Engineer at Wolfspeed. His team at Wolfspeed uses simulation in the design of high-performance, extreme environment wide band gap power semiconductor packages. “I can foresee simulation apps becoming the primary tool used by our engineers.”
The thermal properties of a finned pipe are derived from the results of a conjugate heat transfer simulation. The app user can change aspects of the design such as the arrangement of the inner grooves and outer fins.
Extensive Library of Apps in Version 5.2
To demonstrate the power of the Application Builder, a plethora of new apps have been added to the extensive Application Libraries showcasing the capabilities of the Application Builder. The Application Libraries include apps ranging from membrane dialysis, water treatment, thermoelectric cooling, heat exchangers, touchscreen design, magnetic prospecting, piezoacoustic transducers, muffler design, MEMS sensors, and pressure vessels.
This simulation app is intended for the simulation of mixers equipped with axial or radial impellers. For a given geometry, the application computes the efficiency of the mixing process. The vessels, which are available in three different shapes, can also be equipped with baffles and any of eleven different types of impellers.
Hundreds of Updates to COMSOL Multiphysics, COMSOL Server, and Add-On Products
Version 5.2 provides new core functionality features inspired by feedback from the growing COMSOL Multiphysics user community. For example, users can now add annotations to 3D and 2D plots. A new tetrahedral meshing algorithm minimises the need for manual interactions when meshing large CAD models. Mesh Parts are introduced for integrating STL surface meshes and NASTRAN volumetric meshes into the geometry building work flow. The use of selections is expanded upon and can now be used for singling out which parts of a solution should be used in results processing and visualisations.
Version 5.2 also introduces enhancements to the existing functionalities of COMSOL Multiphysics and its add-on products. Users will benefit from more flexible licence management, allowing them to work on their designs knowing that if the connection to the licence manager is disrupted they have the option to save their files and resume once a connection is re-established. Users of the Structural Mechanics Module and the AC/DC Module will benefit from the new External Materials functionality allowing materials to be algorithmically defined by shared library files written in the C language. The most prominent use of this new functionality will be for nonlinear materials that include hysteresis (history dependency) and irreversibility effects.
