![]() Part 5: Mesh Refinement, CAD Import, and Simulation Apps Overview of the stationary solution approach.Part 4: Using the Solver Algorithms and Addressing Modeling Issues Adding your own user-defined nonlinearity.Part 3: Evaluating Results and Introducing Nonlinearities in a Current-Driven Model Using selections to simplify the model setup.Adding and coupling another physics into the model.Verifying the results via mesh refinement.Extracting numerical results via integration.Part 2: Performing a Mesh Refinement Study and Using Selections and Variables Simplifying the geometry via virtual operations.Getting started with the user interface.Part 1: Electro-Thermal Mechanical Workflow and CAD Import ![]() A chip with an array of bond wires (left) of which we break out and study a single bond wire (center) and then use it for the model geometry (right) as we conduct analyses through the course. An overview of the topics covered throughout the course are as follows: Chip with bond wire array, single bond wire, and bond wire model geometry. The heating leads to thermal expansion and thermally induced stresses. The example model built and used during the course simulates the heating of an array of bond wires connecting a chip to a circuit board. Thus, this course is useful for anyone who is just getting started in the software and learning how to use it. Model files are included in each part of the course, so you can follow along on your own time. You will also obtain a thorough overview of how to use the software in general. Through comprehensive, step-by-step demonstrations in the COMSOL ® software, you will learn how to effectively perform electro-thermo-mechanical analyses. This 5-part, self-paced course is an introduction to the workflow in the software and to modeling Joule heating and thermal expansion in COMSOL Multiphysics ®.
