Modeling Convective Cooling of Electrical Devices

June 23, 2014

One of the main issues with high-power electrical devices is thermal management. Together with BLOCK Transformatoren-Elektronik GmbH, we created a model using COMSOL Multiphysics simulation software that encompasses all of the important details when modeling heating of high-power electrical devices. To do so, we had to utilize high performance computing (HPC) with hybrid modeling. Here, we will discuss how to approach this real-life task with the COMSOL software.

How to Manually Work with Entity Numbers in Selections

June 4, 2014

In Part 1 of this blog series, I introduced how you can export a model M-file from COMSOL Multiphysics® simulation software to learn about the structure of the COMSOL Application Programming Interface (API). One important part of a model M-file is the selections that are made in order to set up properties for the domain, boundaries, etc. These selections are identified using numbers. Here, we explain how you can automate the handling of the entity numbers using LiveLink™ for MATLAB®.

Parameter Optimization with the LiveLink™ Products

May 29, 2014

The most streamlined way to find solutions for your design parameters is to use parameter optimization with the LiveLink™ products. This is helpful when you know what results you want, but you don’t know the optimal parameter values that lead to them.

Best Practice for Working with Model M-Files

May 14, 2014

When developing models in COMSOL Multiphysics® software, it is common to come across tasks that have to be carried out repeatedly. This three-part blog series will show you how repetitive tasks can be efficiently achieved using model M-files and LiveLink™ for MATLAB®.

Using MATLAB® Functions in Your COMSOL Multiphysics® Models

April 18, 2014

Did you know that you can use MATLAB® functions in your COMSOL Multiphysics® models? Well, you can, and in this video tutorial we will show you how, using LiveLink™ for MATLAB®.

How to Create a Material Database from Spreadsheet Data

March 31, 2014

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.

Synchronizing Selections Between SolidWorks® and COMSOL Multiphysics®

March 26, 2014

When working with both SolidWorks® and COMSOL Multiphysics® via LiveLink™ for SolidWorks®, you can choose to synchronize selections. Here’s why you should and how to do it.

Solutions as Starting Point Values with LiveLink™ for MATLAB®

March 10, 2014

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®.
