A pair of bolts on the other end of the busbar are grounded, thus establishing an electrical potential difference. An electric potential is applied to the single bolt on one end. The busbar is made of copper and contains bolts made out of titanium. To demonstrate the use of the modeling workflow, we simulate the Joule heating of a busbar. 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 help the learning process, there is a streamlined workflow you can follow that is reflected throughout the user interface of the software.įollow 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: 4.3.A proper introduction on how to set up and run a model in COMSOL Multiphysics ® is essential when learning how to use the software.Add-on modules provide specialized functionality for electromagnetics, structural mechanics, acoustics, fluid flow, heat transfer, and chemical engineering. 4.3.1 Finite Element Method Procedure in COMSOL Multiphysics The COMSOL Multiphysics software brings a user interface and experience that is always the same, regardless of engineering application and physics phenomena.Interest for setting up simulations from first principles. However, where a preset physics model is not available, it is possible to create new physics model interfaces by directly implementing the physical governing PDEs of the problem of Its library of physics models is really huge and it can be useful for different analysis and applications. It has a user-friendly multiple windows interface incorporating geometry generation, physics model, meshing, solver, and post-processing.ĬOMSOL Multiphysics ® has the capability to solve coupled multiphysics problems, such as electro-thermal and thermo-mechanical phenomena. In the engineering field, including automotive and electronics. In this way, it is possible to focus on the structure, material properties, physics, and boundary conditions under analysis.ĬOMSOL Multiphysics ® is a commercial finite element analysis software for modeling and simulating a wide spectrum of FEM-based physical problems, especially coupled phenomena, The FEM procedure is hidden in the commercial software, which provides only the results of the analysis. The rapid development of commercial FEM softwares enables users to perform finite element analysis by hiding the finite element formulation of the problem of interest. Powerful hardware provides analysis for complicated structure and/or physical phenomena as well as faster calculations. Strong comprehension of both the theory and mathematics behind of the FEM.įurthermore, the extension of the finite element analysis to 2D and 3D modeling makes the FEM procedure even more complicated.ĭue to the prevalence of advanced computer hardware and software, performing a finite element analysis is accessible even for users without much knowledge of the FEM . The procedure to perform a finite element analysis presented in Section 4.2 is not straight forward, because it requires a ![]() Numerical Implementation with Finite Element Method Previous: 4.2.6 Solution of the Linear Equations SystemĤ.3 Simulation Implementation in COMSOL Multiphysics Next: 4.3.1 Finite Element Method Procedure in COMSOL Multiphysics Up: 4. 0:00 / 8:49 (01) Simple Dipole Step by Step - COMSOL 4.2 Tutorial softhummingbird 5.11K subscribers Subscribe 416 Share 172K views 11 years ago Comsol 4.2 - Tutorials Seminar download. ![]()
