Assigning Multiphysics to a Model in COMSOL Multiphysics®
In COMSOL Multiphysics®, there are many different ways you can define the physics settings for a model involving multiple physical phenomena. Your options include the fully automatic approach and the manual approach using predefined couplings.
The fully automatic approach involves using any of the predefined multiphysics interfaces in COMSOL Multiphysics®. When using this approach, all of the individual physics interfaces, multiphysics coupling features, and optimal settings for computing the combination of physics involved are automatically included.
The manual approach using predefined couplings involves manually adding each individual physics interface and then using predefined multiphysics couplings between the interfaces. Using this approach enables you to build up to the full multiphysics model.
Watch this video to learn how you can define the physics for a multiphysics model using either approach. We will also go over the advantages of each approach.
