COMSOL Modeling & Workflow
Taught by Pablo Ferrada, Antonio Atienza Márquez and Alejandro Cifuentes López
This course will provide students with a structured overview of the COMSOL Multiphysics environment and its core modeling workflow. The aim is to familiarize participants with the modeling interface, the creation and configuration of models, and basic numerical methods, with a focus on multiphysics applications. After taking this, you will know the basic utility and functionality of COMSOL Multiphysics for simulation in Science and Engineering. You will also be able to list, identify and use the basic modeling methods, such as model builder, component node, physics nodes, physics interface selection, model convergence and accuracy analysis, boundary conditions, etc.
Geometry generation, material selection and management and meshing process are necessary and important steps in the multiphysics modeling workflow. In this course we will use and study in depth all the tools available in COMSOL Multiphysics to perform them efficiently.
Finally, once the solutions have been calculated, it is necessary to undertake the final task of analyzing, representing, processing and extracting the required results. We will describe all the functionalities for the visualization and analysis of the results, as well as the management of datasets. We will show and practice the methods available for the extraction of derived values in tables, the generation of graphical representations, the management of graphical groups, the export of data and images and the generation of reports.
By the end of the course, students will be able to build simple and complex multiphysics models, define key physical and geometrical parameters, and visualize simulation results effectively.
