About the COMSOL API

You can use the COMSOL API to develop custom applications based on COMSOL. The easiest way to create such applications is by using the Application Builder available with the COMSOL software.

You can run Java class files with COMSOL API-based applications in different ways:

•	In the Application Builder as part of methods that you add using the Method Editor in the Application Builder’s development environment (see also the Application Programming Guide)

•	From the COMSOL Desktop®. A model created using a class file appears automatically in the Desktop.

•	From a batch sequence in a study.

•	Using the comsol batch command.

The LiveLink™ for MATLAB® operates using the COMSOL API and additional utility M-file functions. See the LiveLink™ for MATLAB ®User’s Guide for additional information.

Code examples for the individual API functions in this guide show what the code looks like when using Java® and when using the LiveLink™ for MATLAB®.
