Using the Help Tools in COMSOL Multiphysics® for Modeling Guidance
Within the COMSOL Multiphysics® software, you have access to Help tools to guide you along your modeling process, including the Help, Documentation, and Application Libraries windows.
How to Run Simulations in Batch Mode from the Command Line
Do you find yourself creating new models in the COMSOL Multiphysics® software faster than you can launch them interactively in the COMSOL Desktop® environment? If having to wait for your current model to finish solving before launching the next one does not sound appealing, it’s time to learn how to run your simulations in Batch mode from the command line. As it turns out, this is quite a simple process.
Navigating the Intuitive COMSOL Multiphysics® Modeling Environment
Simulation is a powerful tool that enables you to obtain a holistic view of your design’s performance. While the physics you are studying may be complex, the environment in which you run such studies doesn’t have to be. This rationale has served as the logic behind continuously optimizing the user interface (UI) in the COMSOL Multiphysics® software for ease-of-use. Several tutorial videos, three of which are highlighted here, guide you on how to navigate the environment and utilize its tools.
Implementing a Thermostat with the Events Interface
A thermostat is a device that senses the temperature of a system and uses this information to control the system’s heaters, or coolers, to keep the temperature close to a desired setpoint. While there are many different types of thermostats, we will focus today on one that turns a heater either on or off based upon two setpoints. This is known as an on-off or a bang-bang controller, and it can be implemented with the Events interface in COMSOL Multiphysics.
COMSOL Multiphysics 5.0 Brings User Interface Improvements
Around this time last year, we introduced a new ribbon user interface to COMSOL Multiphysics. Now, with version 5.0, we are introducing many improvements that make COMSOL Multiphysics more intuitive to use. Updates include a change in color scheme, additional multiphysics interfaces, a materials tab, global materials, and Material Sweeps and Function Sweeps.
Dedicated Multiphysics Node Introduced in COMSOL 4.4
To make it easier and more transparent to define models involving multiple physics phenomena in COMSOL, a separate Multiphysics node has been added as a new feature in COMSOL version 4.4. The Multiphysics node gives you control over the couplings for thermal stress and electromagnetic thermal effects involved in your models. Future versions will include further multiphysics couplings through the Multiphysics node in addition to the multiphysics couplings methods already available since previous versions.
Video Tutorial: Introducing the New User Interface in COMSOL 4.4
Each COMSOL release aims to create a better modeling experience for our users, usually in the form of new add-on modules and new functionality in existing products. COMSOL 4.4 brings you all that, but it also includes another significant change: a brand new user interface (UI). The new UI contains a ribbon at the top of the interface (for our Windows® users) to make your modeling easier and faster. The ribbon gives you direct access to the functions you would […]
Philosophy of the Ribbon
Over the past few years, Microsoft® has introduced updates to the user interface (UI) for its Office programs. Microsoft® Office 2013 is all about being touch-screen friendly, and Microsoft® Office 2007 brought the Ribbon interface. The Microsoft® Ribbon was designed to be easier to use than the nested drop-down menus of yore. These days, it’s what we’re used to seeing when working with their tools — and we’ve come to appreciate the ease-of-use, guidance, and clear workflow overview it provides. […]
