Abstract
 Most engineering systems are complex and multidisciplinary in nature. Multiphysics simulators are thus, an essential tool in both engineering education and design. Multiphysics simulators complement practical experiments and can even serve as an excellent alternative to them in many situations. In education, students can use these simulators to construct real life engineering applications in minutes and analyze their behavior. Parametric studies carried out using these simulators can help them understand basic engineering laws and physics phenomena. In design, multiphysics simulators are invaluable for a designer. It allows designers to verify their preliminary designs and modify them until satisfactory performance is achieved without resorting to expensive prototype construction and reconstruction.  The goal of our presentation is to introduce to the audience the motivation for using multiphysics simulators, the basic steps of constructing a multiphysics simulation (geometry definition, boundary conditions definition, meshing, solver configuration and postprocessing) as well as a summary of important concepts that must be clear in the mind of a multiphysics simulator user to avoid obtaining inaccurate results. Case studies from multidisciplinary engineering applications are included for illustration.
