How to Add Stop Conditions to Solvers in COMSOL Multiphysics®

May 17, 2017

Learn how to implement stop conditions for time-dependent and parametric solvers in COMSOL Multiphysics®, as well as scenarios for when and why you should.

How to Use the Find and Auto Completion Tools for Faster Model Setup

May 8, 2017

Looking for a way to set up your models faster? 1 approach is by using the Find and Auto Complete tools. We discuss how to use these tools and demonstrate in an embedded tutorial video.

How and When to Open Recovery Files in COMSOL Multiphysics®

February 7, 2017

If, by chance, the software shuts down before your simulation converges, just use the Open Recovery File feature to pick up where you left off and find your model’s solution.

Using the Help Tools in COMSOL Multiphysics® for Modeling Guidance

January 10, 2017

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

December 20, 2016

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

June 28, 2016

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

February 19, 2015

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

November 5, 2014

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.
