Setting Up and Running a Simulation with COMSOL Multiphysics^®

A proper introduction on how to set up and run a model in COMSOL Multiphysics^® is essential when learning how to use the software. To help the learning process, there is a streamlined workflow you can follow that is reflected throughout the user interface of the software.

Follow along with this tutorial as we guide you through the entire model building process and provide you with a detailed overview of the modeling workflow, which consists of the following steps:

• Set up the model environment
• Build the geometry
• Specify material properties
• Define physics boundary conditions
• Create the mesh
• Run the simulation
• Postprocess the results

You will also learn how to use the Application Builder, which allows you to transform a finite element model into an easy-to-use simulation application.

To demonstrate the use of the modeling workflow, we simulate the Joule heating of a busbar. The busbar is made of copper and contains bolts made out of titanium. An electric potential is applied to the single bolt on one end. A pair of bolts on the other end of the busbar are grounded, thus establishing an electrical potential difference. The temperature in the busbar rises due to resistive heating. In this model, we will couple two physics: electrical currents and heat conduction.

After completing this tutorial, you can learn more about each step in the modeling workflow through the COMSOL Learning Center.
