Modeling in COMSOL Multiphysics involves a lot of tasks, such as choosing the right physics, defining the geometry, and setting up boundary conditions and domain settings. Additionally, material properties have to be defined for the materials included in the model. Such material data may come from the Material Library, but it often has to be obtained experimentally or from literature and imported into COMSOL Multiphysics.

There are several techniques out there for saving memory when solving a model. One involves splitting it into separate sections and solving these individually, instead of the entire model at once. If you want to map data from one COMSOL Multiphysics® solution to the next using MATLAB® scripting, you can do so by connecting the two software programs via LiveLink™ for MATLAB®.

When you are working with foreign CAD data, such as files in STEP or IGES file formats, you may think that you need to re-import a new CAD file and start your modeling over from scratch if you want to study a change in size or shape. But, in fact, you can modify the geometry that you’ve imported with some clever usage of the Deformed Geometry interface in COMSOL Multiphysics. Here, we will look at how this can be done.

Households and industries alike depend on reliable electrical power. To serve the diverse power needs of end users and consumers, the electrical grid is undergoing a major overhaul to upgrade a technology that is over 100 years old. The new infrastructure — the smart grid — is being developed for reliable, economic, and environmentally friendly electrical systems. A great example of equipment for the smart grid comes from ABB. Along with many other products, ABB has introduced the world’s fastest […]

Starting the design process by testing on a small scale is often the best way to tackle issues affecting large objects, like a ship. Detailed in COMSOL News 2013, researchers at INSEAN, The Italian Ship Model Basin, used small-scale testing and then simulation to analyze the effect of placing a sonar system within the bulbous bow at the hull of a ship. Using a small-scale model of a bulbous bow, the researchers at INSEAN performed fluid-structure interaction experiments, and subsequently […]

There are many necessary steps required in order to create a superior product. Based on some initial (or existing) design, you first need to evaluate the physical characteristics of the system. Once some level of understanding of the system has been obtained, it should then be possible to refine and optimize the design based on some reasonable choice of a figure of merit for a good design. The final stage is to prototype the design, which is where 3D printing […]

Starting with the release of COMSOL Multiphysics® 4.3b you can work with multiphysics simulations right from the user interface of the Autodesk® Inventor® CAD system. Called the One Window interface, this functionality is available with LiveLink™ for Inventor®. The result of the work by our external interfaces and integrations development team, the One Window interface, is a completely new environment for simulations that are embedded in the Inventor® user interface. It contains the Model Builder, Settings, and all other views […]
