Getting Started with Building Simulation Apps

This course is an introduction to building simulation applications of a COMSOL Multiphysics model using the Application Builder. In this course, you will be guided through the basics of building your first simulation app. From there, you will explore using a few of the different layout templates available for simulation apps and experience firsthand how quickly and easily you can get started developing your own apps. Throughout the course you will learn various ways of customizing and extending the functionality and operation of the apps you develop. This is accomplished through using various parts of the Application Builder workspace like the Main Window editor, Form Editor, and Method Editor, as well as various tools like the Editor Tools window, Data Access functionality, and Record Method tool. Additionally, you will learn techniques to expedite the app building process.

The simulation app developed in part 7 of the course.
