However, it does require more steps and effort to implement before you reach the full multiphysics model setup and solution. It enables you to narrow your focus on one physics interface or combination of physics interfaces at a time. This approach is advantageous for many reasons. Your multiphysics simulation is broken up into multiple studies as you incrementally add and build upon each physics interface one-by-one gradually, until you have reached the scope of the full multiphysics problem. This is why this modeling strategy is referred to as the manual approach with predefined couplings. These potential setbacks can be minimized if not entirely eliminated through using an incremental methodology that is logically ordered according to the physics involved and the multiphysics interaction being simulated. Computing such a model can become even more time consuming if you encounter solver errors or want to change any of the physics settings and then recompute the model. When modeling multiple physical phenomena, your simulation can be computationally expensive, depending on the spatial dimension, size of mesh elements, and number of physics interfaces involved, among other factors. In Part 2 of the course, we introduce the manual approach with predefined couplings. The Select Physics window, wherein a multiphysics interface has been added to the model. We also introduce the aforementioned example that is used throughout the course the thermal microactuator tutorial model. In Part 1 of the Learning Center course, we discuss how the automatic approach lets you more quickly dive into defining the physics for a multiphysics model without being hampered by all the details. Adding these interfaces to your model makes the modeling process simple, since their use automatically adds the necessary physics interfaces and multiphysics coupling features to your model all at once. This includes the solvers used when computing the model and the default plots generated for the solution. The use of this approach requires the least amount of steps and effort on your behalf.īy automatic, we mean to use the predefined multiphysics interfaces readily available in COMSOL Multiphysics, as well as automatically preconfigured settings for the multiphysics interactions being simulated. In the first part of the course, we introduce the fully automatic approach. Allows you to gain insight into the various ways that the physics can be coupled, after experiencing a small sample of these various waysĪ plot of the stress results for the thermal microactuator tutorial model, which is the example used throughout the course.Enables you to become knowledgeable in and comfortable working with the example model used.This demonstration accomplishes two things: From there, we progressively move into more and more manual implementations, which typically require more time work and in some instances, intimate knowledge of the equation formulation of the physics involved.ĭuring the course, we demonstrate the use of all three approaches using the same example: a thermal-electrical-mechanical (“tem”) version of the thermal microactuator tutorial model found in the Application Gallery on the COMSOL website.

It is especially helpful if you are just getting started with adding the physics for a multiphysics model. We begin the course by discussing and showing the automated implementation, which is the most convenient and ideal to use in any case. Each approach is advantageous for different modeling scenarios and varies in terms of ease of implementation and amount of effort required from the user. In our new Learning Center course, Defining Multiphysics Models, one approach is covered in each respective part of the course, in the order outlined above. In COMSOL Multiphysics, there are three different approaches: When adding the physics for a multiphysics model, there are a number of ways in which you can handle the physics setup. Learn about our three-part Learning Center course on this topic below…

The COMSOL® software provides a plethora of built-in multiphysics couplings and even enables you to implement your own physics couplings. A major strength of the COMSOL Multiphysics® software is how easily such cross-disciplinary interactions, which we refer to as multiphysics interactions, can be accounted for. However, natural and engineering problems often cross these utilitarian borders. To help understand the complicated universe we live in, we have traditionally compartmentalized physics phenomena into distinct disciplinary specializations.
