LetвЂ™s review this course and point out some related resources as well.We also recommend you visit this page to find out about schedule changes and the latest information about the tutorial. Over five parts, we provide a complete tutorial of how to get started in this area, and the series is a great resource for anyone interested in learning the software in general.

For users of the Microfluidics Module, COMSOL Multiphysics version 5.5 brings inelastic non-Newtonian constitutive relations in two-phase flow, an Interior Slip Wall feature, two new Pair features, Continuity and Initial Interface in the Two-Phase Flow, Phase Field interface, and two new optimization tutorials.Many common engineering problems involve Joule heating, the rise in temperature of a conductive material as current passes through it. In the geometry below in Microfluidics Module Updates. A-vier-Stokes backstep geometry models help to examine the physics of the geometry in the absence of external forces. Multiphysic version 5.2a is solved. The Steady Incompressible flow tutorial in COMSOL.

From there, we examine the mesh and use virtual operations to remove some small geometry features to simplify the mesh, and then we solve and visualize the results. In this example, we work with a COMSOL native CAD file, although there are other options for working with CAD files.Next, we set up the problem of computing the electric currents through the wire by applying a potential difference. Part 1The first video begins by demonstrating how to import the CAD geometry of the chip. As current passes through the wires due to an applied electric potential difference, there is Joule heating, which leads to a variation in temperature, and resultant structural expansion and thermal stresses.Watch the Electro-Thermal-Mechanical Modeling course here. Chemical Reaction Engineering Module.Bond wires on a chip. For this example, we concern ourselves solely with these bond wires.COMSOL Documentation.

We use coordinate-based and Boolean selections to define the thermal boundary conditions that prescribe temperature and radiation, and also approximate free convection. From there, we expand our model to solve for the temperature field within the bond wire. We use integration to extract numerical data from the model and investigate the mesh refinement of the model, a necessary part of building any finite element model.

Once youвЂ™ve gone through this material, you will have a firm foundation in the usage of COMSOL Multiphysics and will be ready to tackle even more challenging topics! Try It YourselfThe geometry files and the model files used during this course are available in the Learning Center course. Closing RemarksThe Electro-Thermal-Mechanical Modeling course is meant to provide not only an introduction to the topics of Joule heating and thermal expansion but also to give a thorough overview of the usage of the software, so it will be useful to anybody who is just getting started.The example chosen here is quite similar to one of the examples we use in the Introduction to COMSOL Multiphysics userвЂ™s guide, which is another great resource if you prefer to follow a written approach as an introduction to the software. Then, we turn the model file into a standalone application using the Application Builder. From there, we move on to consider other geometries and also show how to present visually attractive results.
