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: Thinking about the problem, assume that we arrived at the followingĪpproximations (make sure you understand how we arrived at followingĪpproximations for your future quiz and test): The temperature of the heater isĬonstant at 400K.A proper introduction on how to set up and run a model in COMSOL Multiphysics ® is essential when learning how to use the software. We wish to determine the temperature distribution within the sheath. The entireĪssembly is immersed in a fluid and the system is at steady-state, as shown below. Thickness 0.05 m and which starts 0.05 m away from the center. The order isĪlso variable depending on the complexity of the model.Ĭonsider a cylindrical heating rod which is sheathed by a concentric tube of Not all of these steps are always necessary when building a model.
