Equation-Based Modeling in COMSOL Multiphysics

Application ID: 14863

Partial differential equations (PDEs) constitute the mathematical foundation for describing the laws of nature. This presentation provides an introduction to customizing your simulations by developing models directly with PDEs. Learn how to add ordinary differential equations (ODEs) and algebraic equations to your model. Equation-based modeling is a powerful method eliminating the need for user-written subroutines. Once a system of equations has been defined, you can combine them with any other physics-based user interface in the COMSOL environment. Typical applications for equation-based modeling are: custom materials definitions, phase change, and time-dependent loads and sources.

This application was built using the following:

The combination of COMSOL® products required to model your application depends on the physics interfaces that define it. Particular physics interfaces may be common to several products (see the Specification Chart for more details). To determine the right combination of products for your project, you should evaluate all of your needs in light of each product's capabilities, consultation with the COMSOL Sales and Support teams, and the use of an evaluation license.
